Description

Technical Field

[0001] The present invention relates to a warehousing device, in particular to an intelligent solder paste storage cabinet, and more particularly to a solder paste refrigerator and an intelligent solder paste storage cabinet. Background Art

[0002] Solder paste is a new type of welding material that emerged with the advent of SMT. It is a paste-like mixture formed by mixing solder powder, flux, and other surfactants and thixotropic agents. It is mainly used for welding electronic components such as surface resistors, capacitors, and ICs on the PCB in the SMT industry.

[0003] Before use, solder paste is generally placed in a solder paste bottle and stored in a solder paste refrigerator. When needed, it is taken out, allowed to return to room temperature, and then used. In the prior art, the solder paste refrigerator is a rotating cabinet. An entrance is provided on one side of the rotating cabinet for placing the solder paste bottle into or taking it out of the rotating cabinet. For example, in the patent application with the application number "201810771566.2" and the patent name "A Refrigerated and Temperature-Returned Solder Paste Cabinet", this rotating refrigerator has the following disadvantages:

[0004] 1. The storage capacity of the rotating cabinet is relatively small. Only the outermost feeding positions are used as storage spaces. If the storage positions need to be increased, simply increasing the height can only increase a small number of storage positions.

[0005] 2. To increase the storage positions conventionally, generally the diameter of the rotating cabinet is increased and the height is also increased. This can not only increase the number of feeding layers but also increase the number of feeding positions on the same layer. However, this method will increase the size of the entire solder paste refrigerator, increase the overall width, length, and height of the solder paste refrigerator, increase the space occupation, and also increase the cost extremely high.

[0006] 3. When taking and placing the solder paste, it can only be taken and placed at the same vertical height. After taking and placing at the same vertical position, the solder paste rotating cabinet needs to rotate, which is inconvenient for taking and placing and will affect the taking and placing efficiency.

[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0057] Example 1: See Figures 1 to 13 As shown, a solder paste refrigerator comprises:

[0058] A cabinet 11, wherein a refrigeration chamber 110 is disposed in the cabinet 11, and an inlet 111 is disposed on an outer wall of the cabinet 11 to communicate with the refrigeration chamber 110;

[0059] A rack 12, wherein the racks 12 are multiple and arranged along the width direction or the length direction of the cabinet 11, and the inner ends of the racks 12 pass through the inlet 111 and are inserted into the refrigeration chamber 110;

[0060] A driving device 13, the driving device 13 is installed on the cabinet 11 via a bracket 14, a plurality of limit parts 15 are provided on the output end of the driving device 13, a connecting part 120 is provided at the outer end of each of the material racks 12, each of the limit parts 15 is arranged opposite to a connecting part 120, and the limit parts 15 are driven to connect with or separate from the corresponding connecting part 120;

[0061] When the limiting portion 15 is connected to the connecting portion 120 , the driving device 13 drives the material rack 12 to partially or completely leave the refrigerating chamber 110 or to be sent into the refrigerating chamber 110 .

[0062] In this embodiment, the solder paste is contained in the solder paste bottle 2. Each rack has a plurality of material placement positions 121 for storing the solder paste bottles. The material placement positions are hole positions. The solder paste bottle has a barrel-shaped structure with a larger upper part and a smaller lower part. The lower part of the solder paste bottle is inserted into the material placement position, and the diameter of the upper part is larger than the diameter of the hole position, thereby preventing the solder paste bottle from falling and realizing the support for the solder paste bottle. During use, an access trolley is used to grasp the solder paste bottle and place it into the material placement position of the rack or take it out from the material placement position.

[0063] Among them, in this embodiment, taking the illustrated direction as an example, the horizontal direction is the length direction of the cabinet body, and the longitudinal direction is the width direction of the cabinet body. A plurality of racks are longitudinally arranged from front to back. They can be arranged at intervals from front to back, or can be arranged continuously from front to back. In this embodiment, a plurality of racks are arranged at intervals from front to back (longitudinally arranged). The driving end of the driving device is arranged on the entrance side of the cabinet body. In this embodiment, the entrance is arranged at the top of the cabinet body, and the rack is inserted into the refrigerating chamber from the top of the entrance. In this embodiment, a refrigerating device 112 is arranged on the left or right side of the cabinet body and communicated with the refrigerating chamber to refrigerate the refrigerating chamber. When the rack moves downward and one end of it abuts against the bottom of the refrigerating chamber or is close to the bottom of the refrigerating chamber, the other end of the rack completely closes (seals) the entrance at the position of the rack, so that the refrigerating chamber at this place is not communicated with the outside, ensuring the refrigerating effect. During actual use, in the initial state, all the racks move downward and are inserted into the refrigerating chamber, so that the material placing positions of the racks are all in the refrigerating chamber. When it is necessary to take out the solder paste bottle from one of the racks, or when it is necessary to place the external solder paste bottle on the corresponding rack, the driving end of the driving device moves downward and approaches the top of the cabinet body (or the driving end is close to the top of the cabinet body in the initial state), and then the corresponding limiting part is driven to be connected with the connecting part of the rack directly below it, so that the driving device and the corresponding rack can be connected. Then the driving end of the driving device moves upward, and drives the rack to move upward through the mutually connected limiting part and connecting part, so as to pull the rack upward and expose it from the refrigerating chamber, making the material placing position exposed, and then facilitating the access trolley to put the solder paste bottle into the material placing position of the rack, or take out the corresponding solder paste bottle from the material placing position of the rack. After the taking and placing of the solder paste bottle on the rack is completed, the output end of the driving device moves downward, driving the exposed rack to move downward, so that the rack moves downward and is inserted into the refrigerating chamber until the driving device moves downward in place. At this time, all the solder paste bottles on the rack enter the refrigerating chamber and are refrigerated. At the same time, the top of the rack also closes the entrance at this place, preventing the cold air in the refrigerating chamber from leaking out from the entrance at this place, ensuring the refrigerating effect and reducing energy consumption. Among them, if in the initial state, the driving end of the driving device is close to the cabinet body, that is, the limiting part is close to the connecting part, when it is necessary to take out the corresponding rack, the corresponding limiting part works and is directly connected with the connecting part of the corresponding rack to realize the connection between the rack and the driving device. When the driving end of the driving device moves away from the cabinet body later, the rack can be driven to move upward and exposed from the refrigerating chamber for the taking and placing of the solder paste bottle.

[0064] In the present invention, if it is necessary to increase the storage capacity of the cabinet, only the length, width or height of the cabinet can be increased, and only one direction can be increased (the refrigeration device is still connected to the refrigeration chamber for refrigeration). Preferably, the width of the cabinet, that is, the longitudinal length, is increased. The increase in the width of the cabinet is a multiple of the width of the rack, or a multiple of the distance between adjacent racks. After the width of the cabinet is increased (the cabinet will reserve an entrance and connect to the refrigeration chamber), it is only necessary to increase the corresponding number of racks and limit parts. The cost of transformation is low, the space occupied will be smaller, and only a little space needs to be added (space can be added on one side, such as the X-axis direction, the Y-axis direction or the Z-axis direction, without changing the X, Y, and Z axes at the same time) to increase a larger storage space and increase a larger storage capacity. Moreover, in this embodiment, if the cabinet needs to be enlarged, the cost of transformation is also low, and it only needs to be lengthened toward one side.

[0065] See also Figures 1 to 3 As shown, a plurality of entrances 111 are provided at intervals on the outer wall of the cabinet body 11, and the inner end of each of the material racks 12 (in the present embodiment, the inner end of the material rack is the bottom of the material rack) passes through one of the entrances 111 and is inserted into the refrigeration chamber 110. When the inner end of the material rack 12 is completely inserted into the refrigeration chamber 110, the outer end of each of the material racks 12 (in the present embodiment, the outer end of the material rack is the top of the material rack) will be closed corresponding to the entrance 111.

[0066] In this embodiment, a plurality of entrances are arranged at intervals from front to back on the top of the cabinet, and adjacent entrances have a longitudinal spacing. Each material rack is inserted into the refrigerated chamber through an entrance. When the lower part of the material rack is fully inserted into the refrigerated chamber, the top of the material rack closes the top of the entrance so that the refrigerated chamber will not be connected to the outside through the entrance, thereby preventing the internal cold air from leaking out. This can not only ensure the refrigeration effect, but also reduce the loss of cold air, save energy consumption of the refrigeration device, and reduce costs. Moreover, the entrances are arranged at intervals so that there is a certain distance between adjacent material racks. When each material rack moves up and down individually, it will not interfere with adjacent material racks, thereby ensuring stability during use and preventing the solder paste bottles on the material rack from falling off, thereby ensuring stability during the process of taking and placing the solder paste bottles (materials). At the same time, when a single material rack moves up and out of the refrigerated chamber, only one of the entrances will connect the refrigerated chamber with the outside, which can reduce the escape of cold air and ensure the refrigeration effect as much as possible. More preferably, after the material rack moves up, the bottom of the material rack will block the entrance as much as possible, so that when the solder paste bottles are taken and placed, the connection between the refrigerated chamber and the outside is reduced, saving energy consumption and reducing costs.

[0067] The material rack 12 is provided with a plurality of material placement positions 121 ; both sides of the material rack 12 are slidably connected to the inner wall of the refrigeration chamber 110 via guide rails 122 .

[0068] The guide rails are arranged on both sides adjacent to the entrance. In the present embodiment, a guide rail is arranged on the left and right sides of the material rack respectively, and the guide rails on both sides are respectively connected to the left inner wall and the right inner wall of the refrigerated chamber, wherein the guide rails are double-section guide rails or three-section guide rails, thereby ensuring that the material rack can be normally pulled out of the refrigerated chamber, and can also be normally moved into the refrigerated chamber, and can also play a role in movement guidance.

[0069] See also Figures 1 to 6 As shown, the material rack 12 includes a hollow frame 123 and a plurality of layers 124 disposed in the frame 123, each of the layers 124 is provided with at least one material placement position 121, and the connecting portion 120 is disposed on the top surface of the frame 123;

[0070] The outer walls of the frame 123 on both sides are slidably connected to the refrigeration chamber 110. (If the rack is placed sideways, that is, when it is pulled out, it moves left and right, and the shelf is always set horizontally, so that the axis of the material placement is vertical, ensuring the normal placement of the solder paste bottle).

[0071] The limiting portion 15 is connected to the output end of the driving device 13 via the vertical lifting module 125, and the driving device 13 drives the vertical lifting module 125 to be disposed close to or away from the entrance.

[0072] In this embodiment, the frame is a hollow rectangular structure or a square structure, and the left side wall and the right side wall of the frame are slidably connected to the inner walls of the cold storage chamber on both sides through guide rails respectively, and a plurality of shelf plates are arranged inside the frame, spaced from bottom to top, and the material placement position is arranged on the shelf plates. In this embodiment, the material placement position is arranged along the length extension direction of the shelf plates, that is, a discharge material placement position is arranged on the shelf plates along the length direction, and when the storage and retrieval trolley is used to take and place the solder paste bottle, it is more convenient to take and place the material, and in the process of taking and placing the material, it is outside the cabinet body, and the space for taking and placing the material is larger, and it is more convenient to take and place the material, and there will be no interference from the cabinet body. At the same time, compared with the material placement positions arranged in a ring on the annular plate of the rotary refrigerator, even if the material placement positions on each layer of the shelf plates are less than the material placement positions on the upper layer of the rotary refrigerator, more material racks can be set under the same volume, that is, more material placement positions can be set, and the space utilization rate is higher.

[0073] At the same time, in this embodiment, during the process of taking and placing the solder paste bottles (materials), the driving device only drives one group of material racks to move up and out of the cold storage chamber each time, and the other material racks are all in the cold storage chamber. The material racks in the cold storage chamber will not affect the upward material racks for taking and placing the solder paste bottles.

[0074] In this embodiment, the frame includes a bottom plate 1230, a top plate 1231 and two side plates 1232. The top plate is arranged parallel to and directly above the bottom plate. The bottoms of the two side plates are respectively and perpendicularly connected to both sides of the top of the bottom plate, and the tops of the side plates are perpendicularly connected to the bottom surface of one end of the corresponding top plate. A guide rail is installed on the outer side of each side plate. The inner side of the guide rail is connected to the outer wall of the side plate, and the outer side of the guide rail is connected to the inner wall of the refrigeration chamber. More preferably, both ends of the top plate are located outside the two ends of the two side plates. The length of the top plate is greater than the distance between the two side plates, and the width of the top plate is also greater than the width of the side plates. Both the width and length of the top plate are greater than the width and length of the entrance. The width of the side plate is adapted to the width of the entrance, or slightly less than the width of the entrance. The distance between the outer side walls of the two side plates is less than the length of the entrance. The inner wall of each side plate near the entrance and the distance between the side plate and the inner wall of the refrigeration chamber is the thickness of the guide rail for the installation of the guide rail. In order to ensure that after the material frame is placed in the refrigeration chamber, the material frame can seal the entrance. Therefore, both the width and length of the top plate are greater than the width and length of the entrance. The top plate is located above the cabinet body and covers the entrance, thereby preventing the cold air in the refrigeration chamber from leaking out through the entrance. Among them, a sealing ring can be provided at the outer edge of the bottom surface of the top plate. After the driving device moves downward to drive the material frame to move downward so that the lower part of the material frame enters the refrigeration chamber, the top plate is directly above the entrance. At this time, the sealing ring abuts against the top surface of the cabinet body at the outer edge of the entrance for covering the entrance to prevent the cold air in the refrigeration chamber from leaking from the entrance of the material frame. And, due to the self-weight of the material frame, the sealing ring is pressed down, so that the sealing ring tightly seals the top plate and the cabinet body at the entrance to prevent the leakage of cold air.

[0075] More preferably, if the frame is relatively long, a partition plate 1233 is further provided between the two side plates. The middle part of the shelf is inserted into the partition plate for supporting the middle part of the shelf to prevent the shelf from deforming. Or shelves are respectively arranged on both sides of the partition plate. One end of the shelf is connected to the partition plate, and the other end is connected to the side plate.

[0076] See Figures 3 to 7 As shown, the limiting part 15 includes a limiting member 151 and a driving member 152. The middle part of the limiting member 151 is rotatably connected to the vertical lifting module 125. The driving member 152 is installed on the vertical lifting module 125. The output end of the driving member 152 is rotatably connected to one end of the limiting member 151. The other end of the limiting member 151 is provided with a hook 1510 (the first connecting member);

[0077] The connecting portion 120 is provided with a bayonet 1201. When the driving member 152 drives the limiting member 151 to rotate around the vertical lifting module 125 in the first direction, the hook 1510 is snapped into the bayonet 1201, so that the limiting portion 15 is connected to the connecting portion; when the driving member 152 drives the limiting member 151 to rotate around the vertical lifting module 125 in the second direction, the hook 1510 disengages from the bayonet 1201, so that the limiting portion 15 is separated from the connecting portion 120. Wherein, the first direction and the second direction are opposite. For example, if the first direction is clockwise, the second direction is counterclockwise; if the first direction is counterclockwise, the second direction is clockwise.

[0078] In the present invention, the driving member is a cylinder, an electric cylinder or a combination of a motor and a lead screw. Preferably, in this embodiment, the driving member is a cylinder. There are two installation structures for the cylinder. The first one: the fixed end of the cylinder is rotatably connected to the vertical lifting module, and the output shaft of the cylinder is rotatably connected to the upper part of the limiting member. When the output shaft of the cylinder extends (or the output shaft of the cylinder retracts), it pushes the limiting member to rotate in the first direction, so that the hook is snapped into the bayonet, thereby realizing the connection between the limiting portion and the connecting portion. Subsequently, the driving device can drive the rack to move out of or into the refrigerating chamber. When the output shaft of the cylinder retracts (or the output shaft of the cylinder extends), it pushes the limiting member to rotate in the second direction, so that the hook disengages from the bayonet, realizing the separation between the limiting portion and the connecting portion.

[0079] The second structure: the fixed end of the cylinder is fixedly connected to the vertical lifting module. There is a strip-shaped through groove 1511 above the limiting member 151. The strip-shaped through groove extends along the length direction of the limiting member. The limiting member 151 is rotatably connected to the vertical lifting module 125 through a rotating shaft 1512. The strip-shaped through groove 1511 is arranged above the rotating shaft. A push rod 1513 is provided on the output shaft of the cylinder. The push rod is inserted into the strip-shaped through groove. The diameter of the push rod is equal to the width of the strip-shaped through groove, or the diameter of the push rod is slightly smaller than the width of the strip-shaped through groove, and the diameter of the push rod is smaller than the length of the strip-shaped through groove. During the extension and retraction of the output shaft of the cylinder, the push rod will move in the strip-shaped through groove and push the limiting member to rotate around the rotating shaft, thereby realizing the rotation of the limiting member around the vertical lifting module in the first direction and the second direction, realizing the engagement of the hook and the bayonet, or the hook disengaging from the bayonet. In this embodiment, the second structure is adopted. See Figure 4 、 5 as shown.

[0080] In this embodiment, a relief through groove facing the limiting member is provided on the vertical lifting module. The cylinder is arranged at the top of the vertical lifting module, and the rotating shaft is arranged at the top of the vertical lifting module. When the limiting member rotates in the first direction, the hook is located below the vertical lifting module, so that it can be inserted into the bayonet. When the limiting member rotates in the second direction, the hook disengages from the bayonet. At this time, the hook retracts above the vertical lifting module through the relief through groove, or partially retracts into the relief through groove. In this structure, when the driving device drives the vertical lifting module to move downward, the bottom of the vertical lifting module is arranged as close as possible to the top of the rack, that is, the limiting member is as close as possible to the connecting portion, so that the limiting member can be smoothly connected to the connecting portion.

[0081] In this embodiment, the connecting portion includes a connecting frame 1202 and a hook rod 1203 arranged in the connecting frame 1202. The top of the connecting frame has a hanging interface, and the left and right sides of the hanging interface are communicated with the left and right side walls of the connecting frame. The connecting frame below the hook rod forms a bayonet. When the limiting member rotates in the first direction, the hook is inserted below the hook rod, so as to realize the connection between the hook and the bayonet. Preferably, a hook groove 1515 opening towards one side is formed between the hook and the limiting member. When the hook is inserted into the bayonet, the hook rod is located in the hook groove. At this time, the hook groove is inclined upward from right to left. In this way, when the driving device drives the vertical lifting module to move up and down, the hook rod will not fall out of the hook groove, ensuring the firmness of the connection state between the limiting portion and the connecting portion and the safety during use.

[0082] In the present invention, the driving device can be a driving cylinder, a driving electric cylinder or a combination of a driving motor and a lead screw. Among them, the bracket has a slide rail, and the slide rail is arranged parallel to the moving direction of the rack. The vertical lifting module is slidably connected to the slide rail. When the driving device works, it drives the vertical lifting module to move along the slide rail, so as to ensure the moving track of the vertical lifting module and ensure that the rack moves stably into or out of the refrigerating chamber.

[0083] In this embodiment, the driving device uses a driving cylinder which is vertically arranged, and the sliding rail is also vertically arranged. The driving cylinder is arranged at the rear side of the cabinet body. The driving cylinder can be fixed independently, or fixed on the rear side wall of the cabinet body, or connected to the cabinet body through a bracket. The output shaft at the top of the driving cylinder is connected to the vertical lifting module. By the extension and retraction of the output shaft of the driving cylinder, the vertical lifting module is driven to move up and down, so that the limiting part approaches or moves away from the top of the cabinet body, and then drives the corresponding rack to move up to separate from the refrigerating chamber, or move down into the refrigerating chamber. If the driving device uses a driving electric cylinder, the installation structure of the driving electric cylinder is the same as or similar to that of the driving cylinder. If the driving device uses a combination of a driving motor and a lead screw, the lead screw is parallel to the sliding rail and vertically arranged. Both ends of the lead screw are rotatably connected to the bracket, and the middle part of the lead screw is screwed to the vertical lifting module. The driving motor is connected to one end of the lead screw and is used to drive the rotation of the lead screw. When the lead screw rotates, the vertical lifting module is driven to move up and down along the sliding rail.

[0084] See Figures 8 to 13 As shown, the present invention also provides an intelligent solder paste storage cabinet, which includes a frame 3, a storage trolley 4 and a material rack 5 installed on the frame 3, and also includes the above-mentioned solder paste refrigerating cabinet 1. The storage trolley 4 is arranged between the material rack 5 and the solder paste refrigerating cabinet 1. Among them, the storage trolley is arranged at the front side of the solder paste refrigerating cabinet, and the material rack is arranged at the front side of the storage trolley.

[0085] The storage trolley 4 is used to place the materials (solder paste bottles) on the material rack 5 onto the material rack 3 of the solder paste refrigerating cabinet 1. At the same time, it can also place the materials on the material rack 12 of the solder paste refrigerating cabinet 1 onto the material rack 5.

[0086] In this embodiment, a controller is arranged on the frame and is used to control the operation of the solder paste refrigerating cabinet and the storage trolley.

[0087] During use, there are multiple warming zones 50 on the material rack for temporarily storing the solder paste bottles. When storing materials, external equipment or a manipulator places the solder paste bottles on the warming zones of the material rack. Then, the solder paste refrigerating cabinet pulls out the corresponding material rack from the refrigerating chamber, and the storage trolley then takes out the solder paste on the material rack and places it on the corresponding material placement position of the material rack of the solder paste refrigerating cabinet to realize the storage of materials. When taking materials, the solder paste refrigerating cabinet pulls out the corresponding material rack storing the solder paste bottles from the solder paste refrigerating cabinet, so that the solder paste is above the cabinet body. The storage trolley then takes out the solder paste bottles on the material rack and places them on the material rack, waiting for external equipment or a manipulator to take away the solder paste bottles on the material rack for use. Opposite sensors are arranged on both sides of the warming zone to detect whether there are solder paste bottles placed on the warming zone, so as to facilitate the storage trolley to accurately and quickly grab the solder paste bottles.

[0088] See Figure 9 and12 As shown in Fig. 13, a stirring device 6 and multiple counterweight placing racks 7 are further provided. The stirring device 6 and the counterweight placing racks 7 are arranged beside the access trolley 6. Among them, the counterweight placing racks are arranged on the right side of the feeding rack, and the stirring device is arranged on the right side of the counterweight placing racks. Counterweights 70 are placed on the counterweight placing racks 7. The access trolley can grab and place materials and counterweights on the stirring device, and can also grab and place materials and counterweights on the feeding rack and the counterweight placing racks.

[0089] In this embodiment, referring to Figure 12 As shown in Fig., there are four paste bottle clamping components 61 arranged in a circular pattern on the stirring device 6. The paste bottle clamping components 61 are used for clamping the paste bottles. The 4 paste bottle clamping components are installed on a positioning frame 62. The positioning frame 62 is rotatably installed on a stirring bracket 63. A stirring motor 64 is provided on the stirring bracket 63. The stirring motor 64 drives the positioning frame to rotate. A stirring driving cylinder 65 (the stirring driving cylinder is a pneumatic cylinder or an electric cylinder) is also provided on the frame. The bottom of the stirring bracket is rotatably installed on the frame. The fixed end of the stirring driving cylinder is rotatably connected to the frame, and the driving end of the stirring driving cylinder is rotatably connected to the stirring bracket. The stirring driving cylinder is used to drive the positioning frame to rotate around the frame. The stirring motor drives the positioning frame to rotate, so that the paste in the paste bottle clamped by the paste bottle clamping components is stirred. Among them, since the paste is stored in the refrigerated chamber, the paste in the paste bottle will precipitate to the bottom of the paste bottle. After it is taken out, the precipitated paste will affect normal use. Therefore, by placing it on the feeding rack, the paste can be preheated at room temperature first. At the same time, by installing it on the paste bottle clamping components and using the stirring motor to drive the positioning frame to rotate, the paste in the paste bottle can be stirred and not precipitate, ensuring the normal use of the paste. The paste bottle clamping components are electric claws or claws of other structures, which can clamp and release the paste bottles and counterweights. The function of the stirring driving cylinder is mainly to drive the positioning frame to rotate around the frame. When the paste bottle needs to be loaded into the paste bottle clamping components or taken away from the paste bottle clamping components, in order to facilitate the taking and placing of the paste bottle, the stirring driving cylinder drives the stirring bracket to rotate, so that the corresponding paste bottle clamping component is perpendicular to the horizontal plane, or as perpendicular as possible, so that the access trolley can conveniently take the paste bottle from the paste bottle clamping component or put the paste bottle into the paste bottle clamping component for clamping. After the paste bottle is placed and needs to be stirred, the stirring driving cylinder drives the bracket to rotate, so that the paste bottle clamping component is not perpendicular to the horizontal plane. When the subsequent stirring motor drives the stirring bracket to rotate, the paste in the paste bottle can be quickly stirred to ensure the stirring effect.

[0090] Since it is not possible to ensure that each time the solder paste bottle is taken out for stirring, the number is always an even number such as 2 or 4. In order to ensure the balance of the positioning frame during rotation and extend the service life of the positioning frame, when using the stirring device to stir a single solder paste bottle, the balance is poor. Therefore, a counterweight block is also provided. The counterweight block has different weights and is used to counterweight solder paste bottles of different weights, so as to improve the balance performance during the stirring process of the stirring device, thereby ensuring the stability of the use of the stirring device, reducing the maintenance rate, and extending the service life.

[0091] See Figure 9 、 13 As shown, a barcode scanning device 71 is also provided on the counterweight placement rack, and a rotating weighing mechanism 72 is provided beside the barcode scanning device.

[0092] The barcode scanning device is used to connect to the controller. A barcode will be attached to the solder paste bottle. The barcode scanning device is a barcode scanner or other device that can scan the barcode. When discharging (when taking out the solder paste bottle from the intelligent solder paste storage cabinet), the barcode scanning device can scan the barcode on the solder paste bottle to record the usage record of the corresponding solder paste bottle. The rotating weighing device includes a rotating driving part and a weighing mechanism. The rotating driving part is a rotating motor or a rotating cylinder, and the weighing mechanism is an electronic scale. The electronic scale is signal-connected to the controller. The rotating driving part drives the electronic scale to rotate. When discharging, the access trolley will take out the solder paste bottle in the solder paste refrigerator and place it on the electronic scale in advance (there is a feeding space on the electronic scale, and the lower part of the solder paste bottle is placed in this feeding space). The electronic scale will weigh the solder paste bottle to know the weight of the solder paste bottle, and know whether the solder paste bottle is full, at the end, or half full (for example, if the solder paste bottle has a capacity of 90g and contains 90g of solder paste, it is full. If it has been used and not used up, and the weighed weight is less than 90g, greater than 10g or a certain weight, it is half full. If the weight is only the weight of the solder paste bottle itself, or only a little heavier than the weight of the solder paste bottle, it is at the end), so as to facilitate subsequent arrangements for how to use the corresponding solder paste bottle and timely change the material during subsequent use. Since the barcode is attached to one side of the solder paste bottle and the barcode scanning device is provided beside the rotating weighing mechanism, when the solder paste bottle is placed on the rotating weighing mechanism, the barcode may not be directly facing the barcode scanning device, resulting in the problem that it cannot be scanned. Therefore, the rotating driving part drives the weighing mechanism and the solder paste bottle above it, so that when the solder paste bottle rotates, the barcode will definitely pass through the barcode scanning device and be scanned by the barcode scanning device, so that the solder paste bottle is recorded.

[0093] See Figure 10 、 11As shown, the access trolley 4 includes a trolley 41, a fork 42 and a driving mechanism. The driving mechanism includes a horizontal driving mechanism 43, a vertical driving mechanism 44, a rotary driving mechanism 45 and a fork driving mechanism 46. The horizontal driving mechanism 43 is configured to drive the trolley 41 to move horizontally on the rack 3 between the loading rack 5 and the solder paste refrigerator 1. A first bracket 47 is vertically movably installed on the trolley 41. The vertical driving mechanism 44 is installed on the trolley 41 and is configured to drive the first bracket 47 to move vertically along the trolley 41.

[0094] In this embodiment, the horizontal driving mechanism can be a combination of a motor and a lead screw, or a combination of a motor and a belt, or a combination of a motor, a gear and a rack, as long as it can drive the trolley to move horizontally along the rack. A horizontal slide rail 33 is provided on the rack. The horizontal slide rail is arranged at the bottom of the rack between the solder paste refrigerator and the loading rack. The bottom of the trolley slides on the horizontal slide rail (in order to ensure the stability of operation, a horizontal slide rail can also be provided at the top of the rack, and the top of the trolley slides on the horizontal slide rail at the top). If the driving device adopts a combination of a motor, a gear and a rack, the rack is arranged on the horizontal slide rail along the extension direction of the horizontal slide rail. The motor is installed on the trolley, the gear is arranged on the output shaft of the motor, and the gear meshes with the rack. By the operation of the motor, the trolley is driven to move along the horizontal slide rail. Of course, there can also be other driving structures as long as the trolley can be driven to move along the horizontal slide rail.

[0095] More preferably, a plurality of rubber-coated rollers are respectively arranged on the front side and the rear side below the trolley. The inner wall of the rubber-coated roller abuts against the side wall of the horizontal slide rail. When the trolley moves horizontally, due to the arrangement of the rubber-coated rollers, the stability of the trolley during movement can be effectively guaranteed, the vibration is reduced, the movement is smoother, and the noise is smaller, so that the fork can be driven to move in the X-axis direction. The vertical driving mechanism preferably adopts a combination of a vertical lead screw and a motor (it can also be other structures). A vertical slide rail is vertically arranged on the trolley. The first bracket slides vertically on the vertical slide rail. The vertical lead screw is arranged parallel to the side of the vertical slide rail. The motor drives the vertical lead screw to rotate. The middle part of the vertical lead screw is screwed to the first bracket, so as to drive the first bracket to move vertically along the trolley, thereby driving the fork to move in the Z-axis direction.

[0096] See Figure 10 As described, a second bracket 48 is rotatably installed on the first bracket 47. The rotary driving mechanism 45 is installed on the first bracket 47 and is configured to drive the second bracket 48 to rotate around the first bracket 47.

[0097] The rotation drive mechanism can adopt a combination of a motor and a gear, or a rotary cylinder. In this embodiment, a combination of a motor and a gear is adopted. The second bracket is rotatably connected to the first bracket through a vertical shaft. A first gear is sleeved on the vertical shaft. The motor is installed on the first bracket, and a second gear is provided on the output shaft of the motor. The first gear meshes with the second gear. By driving the rotation of the second gear by the motor, through the meshing of the first gear and the second gear, the second bracket is driven to rotate, thereby driving the fork to rotate in the horizontal direction and rotate to different positions.

[0098] See Figure 10 As shown, the fork drive mechanism 46 is connected to the second bracket 48 through the third bracket 49, and the fork drive mechanism 46 drives the fork 42 to open and close;

[0099] A telescopic drive mechanism is provided on the second bracket 48, and the telescopic drive mechanism drives the third bracket to telescopic along the length direction of the second bracket. The telescopic drive mechanism adopts a combination of a lead screw and a motor, or a combination of a motor and a belt. Taking the combination of a motor and a lead screw as an example, the lead screw is arranged parallel to the extension direction of the second bracket, and the motor drives the lead screw to rotate. The middle part of the lead screw is screwed to the third bracket, thereby driving the third bracket to move, and further driving the fork to telescopic along the second bracket, so that the solder paste bottle grabbed by the fork is placed on the racks at different longitudinal positions.

[0100] See Figure 11 As shown, the fork 42 includes two claws 420 arranged oppositely, and a material grabbing space is formed between the two claws 420. The inner ends of the claws 420 are connected to the fork drive mechanism 46, and the fork drive mechanism 46 drives the two claws 420 to approach or move away from each other, so that the fork 420 opens or closes;

[0101] The material grabbing space includes an outer end material grabbing space 421 and an inner end material grabbing space 422 that are communicated with each other, and the width of the outer end material grabbing space 421 is greater than the width of the inner end material grabbing space 422.

[0102] In this embodiment, the solder paste bottles have different capacities, there are large-capacity solder paste bottles and small-capacity solder paste bottles. Therefore, in order to enable the same fork to grab two different-capacity solder paste bottles (solder paste bottles with different capacities and different diameters), therefore, the material grabbing space has an inner end material grabbing space and an outer end material grabbing space with different sizes for grabbing solder paste bottles of different sizes, with a wider application range and lower cost.

[0103] More preferably, a sensor 423 is further provided on the third bracket for detecting whether the fork has grabbed a solder paste bottle.

[0104] In the present invention, a shield 31 is provided outside the frame. A material feeding opening 32 is provided on the shield and is directly opposite to the material feeding rack. The material (solder paste bottle) is put into the intelligent solder paste storage cabinet from this material feeding opening and placed on the material feeding rack (wherein, a cabinet door is provided on the shield. When material feeding is required, the cabinet door is opened to expose the material feeding opening for material feeding). An outlet 34 is also provided, and the outlet preferably faces the rotary weighing mechanism directly. After the solder paste bottle is scanned and weighed, the solder paste bottle can be directly taken out from this outlet. A face recognition device is also provided to identify the operator, so as to grant the operator the operation authority, and the corresponding operator controls the intelligent solder paste storage cabinet to prevent the problem of incorrect operation of the equipment by non-staff or non-operators of this intelligent solder paste storage cabinet.
