Description

Technical Field

[0001] This invention relates to the field of solder paste storage and palletizing technology, specifically to a solder paste storage and palletizing mechanism for a solder paste storage cabinet. Background Technology

[0002] Solder paste storage cabinets are industrial devices specifically designed for storing and managing solder paste (a core material for surface mount technology (SMT) soldering). Through precise temperature control and intelligent management, they ensure the activity and process stability of the solder paste. The temperature is typically controlled between 2-10℃ (some models support independent adjustment of dual temperature zones) to prevent solder paste oxidation or delamination. Anti-condensation technology is employed to reduce the impact of humidity fluctuations on solder paste performance. Solder paste containers are transported to the cabinet via a conveyor mechanism and then categorized and stacked by a storage and palletizing system. The utility model disclosed in CN221369554U is a formula storage type automatic palletizer. It adopts a four-axis gantry palletizer. The palletizing head has the functions of forward and backward, left and right, up and down and 360-degree rotation. It can be freely adjusted according to the carton specifications and stacking requirements. The stacking method, position, direction and number of stacking layers can be freely set and form a formula storage.

[0003] The utility model disclosed in CN221459204U is a gripper module for a solder paste management cabinet palletizer. By designing X-axis, Y-axis and Z-axis components, and cooperating with the gripper components, it realizes independent movement of the X, Y and Z axes, thereby enabling fast and accurate gripping, smooth handling and convenient placement of various solder paste cans. This design improves the degree of freedom of operation and handling efficiency, while optimizing the overall performance and reliability of the solder paste management cabinet.

[0004] However, the palletizing mechanism for solder paste management cabinets disclosed above still has the following problems in actual use: The disclosed palletizing mechanism realizes autonomous storage and palletizing of solder paste, but such palletizing mechanism cannot strictly follow the first-in-first-out storage and use requirements. Some of the first palletized solder paste is stored in the cabinet for a long time, which leads to sedimentation of the batch of solder paste and affects subsequent use. At the same time, random and designated dispensing will also cause gaps in the storage and palletizing area, and the solder paste stored later cannot fill the gaps in time, occupying palletizing storage space and affecting palletizing efficiency.

[0005] Therefore, we propose a storage and palletizing mechanism for solder paste storage cabinets to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a storage and palletizing mechanism for solder paste storage cabinets. This addresses the problem that existing palletizing mechanisms, which achieve autonomous storage and palletizing of solder paste, cannot strictly adhere to the first-in-first-out (FIFO) storage and usage requirements. As a result, some of the first-palletized solder paste is stored inside the cabinet for extended periods, leading to sedimentation of that batch and affecting subsequent use. Furthermore, random and designated dispensing can cause gaps in the storage and palletizing area, which cannot be promptly filled by subsequently stored solder paste, thus occupying palletizing storage space and affecting palletizing efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a storage and stacking mechanism for solder paste storage cabinets, comprising a storage cabinet body, wherein the storage cabinet bodies are stacked vertically according to storage requirements, and the storage cabinet bodies have a rectangular structure with an open front for stacking solder paste bodies; further comprising: The storage cabinet body has storage mechanisms arranged at equal intervals inside, and each storage mechanism includes a storage platform, with a sealing partition fixedly installed at the front end of the storage platform. The storage platform has internal storage guide slots that guide the solder paste in a first-in-first-out manner. A palletizing mechanism is provided below the storage platform, and the palletizing mechanism includes a palletizing conveyor belt. Palletizing pushers are fixedly provided at equal intervals on the outer wall of the palletizing conveyor belt. The palletizing pushers are attached to the outer wall of the solder paste body to realize the palletizing and conveying.

[0008] Preferably, the storage mechanism includes a telescopic side frame, with the front end of the telescopic side frame fixedly installed on the left and right sides of the storage platform, and the rear end of the telescopic side frame fixedly installed on the left and right sides inside the storage cabinet body. The telescopic side frame is used to drive the storage platform to slide inside the storage cabinet body, thereby improving the efficiency of solder paste storage, retrieval and inspection.

[0009] Preferably, the storage mechanism includes storage platforms that are equidistantly arranged inside the cabinet body, and the sealing partitions on the front of the storage platforms are slidably arranged at the front opening of the cabinet body, and the opening of the cabinet body is closed by the adjacently distributed sealing partitions so that the solder paste body can be refrigerated and sealed for storage.

[0010] Preferably, the storage mechanism includes a storage guide groove with an "S" shape that is opened inside the storage platform, and the left and right sides of the front sealing partition of the storage platform are respectively provided with a discharge groove and a feed groove, and the discharge groove and the feed groove are respectively connected to the front end of the storage guide groove.

[0011] Preferably, the storage mechanism includes a feed slot for guiding the solder paste body into a storage guide slot inside the storage platform, and discharges it from the discharge slot after the solder paste body is gradually stacked, so that the solder paste body can realize the first-in-first-out storage stacking and retrieval steps, and the upper end of the solder paste body has a frustum-shaped structure that fits against the upper surface of the storage platform to prevent it from falling off during storage stacking.

[0012] Preferably, the palletizing mechanism includes palletizing shafts, and the two palletizing shafts are arranged in a front-to-back manner and rotatably mounted on the bottom surface of the storage platform. Each set of palletizing shafts is staggered with the storage guide groove, and the lower end of each set of palletizing shafts is engaged with the inner wall of the palletizing track.

[0013] Preferably, the palletizing mechanism includes palletizing pushers fixedly arranged in pairs on the outer wall of the palletizing conveyor, with the end of each set of palletizing pushers extending into the interior of the storage guide groove away from the palletizing conveyor. The spacing between each set of palletizing pushers is greater than the lower diameter of the solder paste body. The palletizing mechanism uses the rotation of the palletizing conveyor to drive the palletizing pushers and the clamped solder paste body to achieve storage and palletizing along the "S"-shaped structure of the storage guide groove.

[0014] Preferably, the palletizing mechanism includes a drive shaft, which is rotatably mounted above the front end of the storage platform via a bearing. The top ends of the drive shaft and the adjacent palletizing shaft are meshed together by a bevel gear set. Furthermore, the bottom surface of the drive shaft is at a higher level than the top surface of the solder paste body inside the storage platform.

[0015] Preferably, the palletizing mechanism includes a transmission gear, which is disposed at the bottom end of the transmission shaft in the middle of the storage platform via a ratchet assembly. The right side of the transmission gear is meshed with the rear end of the transmission rack, and the front end of the transmission rack slides through the front end of the sealing partition. The front end of the transmission rack and the sealing partition are connected to each other by a return spring.

[0016] Preferably, the palletizing mechanism includes a transmission gear that rotates by meshing with a transmission rack, and when the transmission gear rotates, it drives the transmission shaft to rotate in one direction through a ratchet assembly, so that the palletizing conveyor belt drives the solder paste body to perform unidirectional storage and palletizing operations.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The solder paste storage cabinet uses a storage and stacking mechanism to stack the storage cabinet bodies on a storage platform. After the solder paste body enters the storage platform, it moves along the "S"-shaped storage guide groove. The rotating and moving stacking pusher drives the solder paste body at any position to stack, following the first-in-first-out method to avoid the solder paste body from settling and affecting subsequent use. The specific details are as follows: 1. The storage cabinet body is set inside the solder paste storage cabinet and stacked in an up-down manner to reduce the space occupied inside the solder paste storage cabinet. At the same time, the storage platform is slidably installed inside the storage cabinet body through telescopic side frames on the left and right sides. The sealing partition fixedly installed at the front of the storage platform seals the open part of the storage cabinet body so that the solder paste body can be refrigerated and sealed.

[0018] 2. The discharge slots on the left and right sides of the sealing partition are closed by sliding doors connected by hydraulic telescopic rods, and opened when it is necessary to stack the solder paste body. The conveying component drives the solder paste body to move to the discharge slot and push it inward so that it can enter the storage guide channel and move along the shape of the storage guide channel.

[0019] Furthermore, the storage guide channel limits the frustum-shaped structure at the top of the solder paste body, so that the solder paste body follows the first-in-first-out method to be stacked through the storage guide channel. The solder paste body that enters the stack first is at the front of the storage guide channel and is discharged from the discharge slot on the left side of the sealing partition after continuous stacking, so as to avoid the solder paste body from settling and affecting subsequent use.

[0020] 3. The conveying assembly carrying the solder paste body moves to the front of the sealing partition and squeezes the drive rack to move. The meshing drive rack drives the palletizing shaft to rotate through the ratchet assembly. The bevel gear group drives the drive shaft to drive the palletizing shafts on the left and right sides to rotate synchronously, so as to drive the meshing palletizing track and the palletizing push block on the outer wall to rotate and move, thereby conveying the clamped solder paste body.

[0023] 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.

[0024] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: In order to solve the problems existing in the storage and stacking of solder paste bodies 2, this example discloses the following technical solution: a storage and stacking mechanism for solder paste storage cabinet, including a storage cabinet body 1. The storage cabinet body 1 is stacked in the vertical direction according to storage requirements, and the storage cabinet body 1 has a rectangular structure with an open front for stacking solder paste bodies 2; storage mechanisms are arranged at equal intervals inside the storage cabinet body 1, and the storage mechanisms include a storage platform 3, and a sealing partition 4 is fixedly installed at the front end of the storage platform 3.

[0025] The storage mechanism includes a telescopic side frame 8, with the front end of the telescopic side frame 8 fixedly installed on the left and right sides of the storage platform 3, and the rear end of the telescopic side frame 8 fixedly installed on the left and right sides inside the storage cabinet body 1. The telescopic side frame 8 is used to drive the storage platform 3 to slide inside the storage cabinet body 1, thereby improving the efficiency of storing, retrieving and inspecting the solder paste body 2.

[0026] The storage mechanism includes storage platforms 3 that are equidistantly arranged inside the cabinet body 1. The sealing partitions 4 on the front of the storage platform 3 are slidably arranged at the front opening of the cabinet body 1. The opening of the cabinet body 1 is sealed by the adjacently distributed sealing partitions 4 to ensure that the solder paste body 2 is refrigerated and sealed.

[0027] like Figures 1-3As shown, the storage cabinet body 1 is first fixedly installed inside the solder paste management cabinet. According to the actual requirements, the storage cabinet body 1 is stacked up and down to reduce the space occupied, making the storage and stacking operation of the solder paste body 2 more centralized and convenient. At the same time, the storage platform 3 is installed inside the storage cabinet body 1 through the telescopic side frames 8 on the left and right sides, and is distributed at equal distances in a vertical manner. The sealing partition 4 fixedly installed at the front end of the storage platform 3 closes the front opening of the storage cabinet body 1 to prevent oxidation and delamination caused by external temperature when the solder paste body 2 is stored.

[0028] Example 2: In order to solve the problems existing in the storage and stacking of the solder paste body 2, this example discloses the following technical solution, wherein the storage platform 3 is provided with a storage guide 5 inside, and the storage guide 5 guides the solder paste body 2 in a first-in-first-out manner; the storage guide 5 included in the storage mechanism is in an "S" shape and is opened inside the storage platform 3, and the left and right sides of the front sealing partition 4 of the storage platform 3 are respectively provided with a discharge slot 9 and a feed slot 10, and the discharge slot 9 and the feed slot 10 are respectively connected to the front end of the storage guide 5.

[0029] The storage mechanism includes a feed slot 10 for guiding the solder paste body 2 into the storage guide slot 5 opened inside the storage platform 3, and after the solder paste body 2 is gradually stacked, it is discharged from the discharge slot 9, so that the solder paste body 2 can realize the first-in-first-out storage stacking and retrieval steps, and the upper end of the solder paste body 2 has a frustum-shaped structure that fits against the upper surface of the storage platform 3 to prevent it from falling off during storage stacking.

[0030] like Figures 4-6 As shown, during the stacking and storage of solder paste body 2, the sealing partition 4 at the front end of the storage platform 3 picks up and puts in the solder paste through the discharge slots 9 and feed slots 10 on the left and right sides. The discharge slots 9 and feed slots 10 on the left and right sides are closed by sliding doors connected by internal hydraulic telescopic rods. This allows the discharge slots 9 and feed slots 10 to be closed during normal storage and opened during storage and retrieval operations. The solder paste body 2 is fed into the storage platform 3 through the feed slot 10 on the right side by the conveying component. After moving into the storage platform 3, the solder paste body 2 moves along the "S"-shaped storage guide 5. The solder paste body 2 that enters the stack first is at the front of the storage guide 5 and is discharged from the discharge slot 9 on the left side of the sealing partition 4 after continuous stacking. This achieves the first-in-first-out storage and stacking requirement and avoids the solder paste body 2 from settling and affecting subsequent use.

[0031] Example 3: To solve the problems existing in the storage and palletizing of the existing solder paste body 2, this example discloses the following technical solution: A palletizing mechanism is provided below the storage platform 3, and the palletizing mechanism includes a palletizing conveyor belt 6. The outer wall of the palletizing conveyor belt 6 is fixedly provided with palletizing push blocks 7 at equal intervals. The palletizing push blocks 7 are attached to the outer wall of the solder paste body 2 to realize the conveying and palletizing. The palletizing mechanism includes a palletizing rotating shaft 11, and two palletizing rotating shafts 11 are distributed in a front-to-back manner and are rotatably mounted on the bottom surface of the storage platform 3. Each set of palletizing rotating shafts 11 is staggered with the storage guide groove 5, and the lower end of each set of palletizing rotating shafts 11 is engaged with the inner wall of the palletizing conveyor belt 6.

[0032] The palletizing mechanism includes palletizing pushers 7, which are fixedly installed on the outer wall of the palletizing conveyor 6 in pairs. The end of each set of palletizing pushers 7 away from the palletizing conveyor 6 extends into the interior of the storage guide groove 5. The spacing between each set of palletizing pushers 7 is greater than the lower diameter of the solder paste body 2. The palletizing pushers 7 and the held solder paste body 2 are driven to achieve storage and palletizing along the "S"-shaped structure of the storage guide groove 5 by the rotation of the palletizing conveyor 6. The palletizing mechanism includes a drive shaft 12, which is rotatably mounted above the front end of the storage platform 3 through bearings. The top ends of the drive shaft 12 and the adjacent palletizing shaft 11 are meshed and connected to each other through a bevel gear set 13. The bottom surface of the drive shaft 12 is higher than the top surface of the solder paste body 2 inside the storage platform 3.

[0033] The palletizing mechanism includes a transmission gear 14, which is mounted on the bottom end of the transmission shaft 12 in the middle of the storage platform 3 via a ratchet assembly 15. The right side of the transmission gear 14 is meshed with the rear end of the transmission rack 17, and the front end of the transmission rack 17 slides through the front end of the sealing partition 4. The front end of the transmission rack 17 and the sealing partition 4 are connected to each other by a return spring 16. The transmission gear 14 in the palletizing mechanism rotates by meshing with the transmission rack 17. When the transmission gear 14 rotates, it drives the transmission shaft 12 to rotate in one direction via the ratchet assembly 15, so that the palletizing conveyor 6 drives the solder paste body 2 to perform unidirectional storage and palletizing operations.

[0034] like Figures 7-10As shown, the storage cabinet body 1, in conjunction with the conveying assembly, conveys the solder paste body 2 to the feed slot 10 on the right side of the sealing partition 4. During the stacking operation, the conveying assembly approaches the front of the sealing partition 4 to squeeze the transmission rack 17 connected to the inside of the sealing partition 4 via the return spring 16. This causes the transmission rack 17 to move backward, driving the meshing transmission gear 14 to rotate. The rotation of the transmission gear 14 at this time locks the stacking shaft 11 through the ratchet assembly 15. The central stacking shaft 11 then meshes with the transmission shaft 12 through the bevel gear group 13 on the top surface to rotate. This allows the transmission shaft 12 to drive the remaining stacking shafts 11 to rotate through the bevel gear groups 13 on the left and right sides, so that the stacking shafts 11 are evenly distributed and rotate synchronously, moving and stacking the solder paste bodies 2 in various positions in the storage guide slot 5 inside the storage platform 3.

[0035] Furthermore, after the conveying component has finished conveying the solder paste body 2, it moves away from the sealing partition 4 and no longer squeezes the transmission rack 17. The reset spring 16 drives the transmission rack 17 to move outward, causing the meshing transmission gear 14 to rotate in the opposite direction. The ratchet assembly 15 above is in the unlocked state when rotating in the opposite direction, thus not driving the palletizing shaft 11 to rotate, avoiding affecting the normal palletizing operation of the solder paste body 2.

[0036] like Figures 4-6 As shown, when the palletizing shaft 11 on the bottom surface of the storage platform 3 rotates, it drives the palletizing track 6 and the palletizing pusher 7 connected at the lower end to rotate and move. The two palletizing pushers 7 clamp the solder paste body 2. At the same time, the palletizing pushers 7, which are evenly distributed, are staggered below the storage guide 5 so that the solder paste body 2 can be palletized and transported along the "S"-shaped storage guide 5 during the movement. This allows the solder paste body 2 at any position inside the storage guide 5 to be palletized synchronously. Even in multiple operations where no material is stored and only material is retrieved, the first stored solder paste body 2 can be delivered, thereby reducing the space occupied by palletizing and improving the efficiency of palletizing operations.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
