Description

Technical Field

[0001] This utility model belongs to the field of circuit board manufacturing technology, and in particular relates to a workpiece dispensing platform for a fully automatic dispensing machine. Background Technology

[0002] As an automated precision dispensing device, the fully automatic dispensing machine achieves precise and automatic dispensing, filling, and distribution of liquid adhesives, resins, and other materials through a control system, precision mechanical structure, and intelligent operation. As an important component of fully automatic dispensing machines, the dispensing platform serves to provide a stable platform for placing workpieces. Currently, in order to facilitate the cleaning of the surface of the dispensing platform, a cleaning mechanism for manually cleaning the surface of the dispensing platform has also been installed on the dispensing platform.

[0003] A search revealed that authorization announcement number CN211070682U, with an authorization announcement date of July 24, 2020, discloses a workpiece dispensing platform mechanism for a fully automatic dispensing machine. The mechanism includes a platform body, with a dispensing box and a support cabinet mounted on the lower outer surface of the platform body. The support cabinet is located on one side of the dispensing box. A cleaning mechanism is mounted on the upper outer surface of the platform body, and a storage mechanism is mounted on one inner surface of the platform body. This utility model's workpiece dispensing platform mechanism for a fully automatic dispensing machine provides a cleaning function for daily operation, allowing for cleaning of the dispensing platform after use or prolonged use, thus extending the platform's working lifespan. The storage mechanism provides a simple and practical waste collection structure, effectively collecting waste generated during the dispensing process and protecting the external environment.

[0004] Existing technologies achieve the cleaning function of the platform body surface by moving the cleaning plate along the platform body. However, in actual use, manual operation is required to move the cleaning plate. At the same time, the cleaning effect of a single cleaning using the cleaning plate is poor. Furthermore, existing technologies require manual pulling out of the collection box to collect the cleaned items, which is quite cumbersome. Therefore, we provide a workpiece dispensing platform for a fully automatic dispensing machine to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a workpiece dispensing platform for a fully automatic dispensing machine. Motor 1 rotates the brush roller, and together with Motor 2, a scraper removes the material adhering to the worktable surface. The rotating brush roller further cleans the worktable surface. Furthermore, moving the side plate to the right moves the vertical plate and collection box to the right to receive the cleaned material. This solves the problems of existing technologies requiring manual operation to move the cleaning plate, poor cleaning effect during single cleaning, and cumbersome operation requiring manual pulling out of the collection box to collect the cleaned material.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a workpiece dispensing platform for a fully automatic dispensing machine, comprising a worktable, a cleaning mechanism on the outer side of the worktable, a guide rail symmetrically fixed to the front and rear side walls of the worktable, a brush roller above the worktable, a motor 1 behind the brush roller, a scraper plate to the right of the brush roller with its right end in contact with the upper wall of the worktable, a second motor 2 on the lower left side of the worktable, and a screw fixed to the power output shaft of the second motor; and a collection mechanism comprising a collection box located below the right end of the worktable, with vertical plates symmetrically arranged in front of and behind the collection box, and a spring on the side of the vertical plate away from the guide rail.

[0007] The present invention is further configured such that a rectangular strip is provided in the internal gap of the brush roller, a protrusion is fixed at the rear end of the rectangular strip, the protrusion is fixedly connected to the power output shaft of the motor, and side plates are symmetrically provided at the front and rear of the brush roller, and the motor is fixedly connected to the side plate located at the rear.

[0008] The present invention is further configured such that a guide groove is provided on the side wall away from the worktable of the guide rail, and a boss located inside the guide groove is fixed on the side wall of the side plate near the worktable.

[0009] The present invention is further configured such that a positioning sleeve is provided in the internal gap fit of the front end of the rectangular strip, the positioning sleeve is in gap fit with the side plate located on the front side, and a bolt is provided through the inside of the positioning sleeve, and the positioning sleeve is fixedly connected to the rectangular strip by the bolt.

[0010] The present invention is further configured such that an extension strip fixed to the shovel plate is provided on the side of the side plate away from the workbench, and a leak-proof plate fixed to the shovel plate is provided on the side of the extension strip close to the workbench. A positioning rod is fixed at the left end of the front wall of the extension strip located on the rear side, and the positioning rod is in clearance fit with the side plate located on the rear side. A ring is fixed at the left end of the extension strip located on the front side, and a bolt is threaded inside the ring. The rear end of the bolt is a smooth cylindrical surface, and the rear end of the bolt is in clearance fit with the side plate located on the front side.

[0011] The present invention is further configured such that a connecting plate is threadedly connected to the external end of the screw, and the front and rear ends of the connecting plate are respectively fixedly connected to the corresponding side plates. End plates fixed to the worktable are provided on the external ends of both the left and right ends of the screw. The screw is rotatably connected to the end plates through bearings, and the second motor is fixedly connected to the end plate located on the left side.

[0012] The present invention is further configured such that a rotating rod is fixedly provided at the upper end of both the front and rear side walls of the collection box, the rotating rod is rotatably connected to the corresponding vertical plate through a bearing, and a boss II located inside the guide groove is fixedly provided on the side wall of the vertical plate near the collection box.

[0013] The present invention is further configured such that rectangular plate one and rectangular plate two are respectively fixedly provided at the left and right ends of the spring, and rectangular plate one and rectangular plate two are respectively fixedly connected to the corresponding side plate and guide rail.

[0014] This utility model has the following beneficial effects: 1. This utility model, by setting up a second motor, a first motor, a brush roller, and a scraper, utilizes the operation of the first motor to drive the rectangular strip to rotate, thereby causing the brush roller to rotate. Simultaneously, the operation of the second motor drives the screw to rotate, which in turn drives the scraper, which is in contact with the upper wall of the worktable, to move and clean the upper surface of the worktable. This method can clean larger objects on the upper surface of the worktable. The rotating brush roller can further clean the upper surface of the worktable after it has been cleaned by the scraper, removing dust and fine objects. Compared with the prior art, this method achieves two cleaning methods for the upper surface of the worktable through the combined action of the scraper and the brush roller, which can improve the cleaning effect and reduce the labor intensity of workers by eliminating the need for excessive manual intervention.

[0015] 2. This utility model, by incorporating a spring, allows the collection box to be positioned below the worktable under normal conditions. When the shovel moves to the right until the side plate contacts the vertical plate, the side plate moves to the right, causing the vertical plate to move to the right as the second motor continues to operate. This positions the collection box below the right end of the worktable, where it can receive the cleaned items removed by the shovel and brush roller. Driven by the second motor, the side plate moves to the left, and the spring pushes the rectangular plate to the left, ultimately causing the collection box to retract to the right end of the worktable for concealment. Compared to existing technologies, this method automatically pushes the collection box to the right end of the worktable when cleaning, placing it in the position to collect the cleaned items. After the second motor drives the brush roller and shovel back to their original positions, the elastic element moves the collection box to the bottom of the worktable for concealment. This eliminates the need for excessive manual intervention in the cleaning process, simplifying the operation. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1 Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This is the first embodiment of the present invention, which provides a workpiece dispensing platform for a fully automatic dispensing machine, including a worktable 2 for placing workpieces to be dispensed. A cleaning mechanism 1 is provided on the outer side of the worktable 2. The cleaning mechanism 1 includes guide rails 104 symmetrically fixed to the front and rear side walls of the worktable 2. A brush roller 102 is provided above the worktable 2. The bottom of the bristles fixed to the outer peripheral wall of the brush roller 102 contacts the upper wall of the worktable 2. A motor 101 is provided behind the brush roller 102. The brush roller 102 is driven to rotate. A scraper 103 is provided on the right side of the brush roller 102. The right end of the scraper 103 contacts the upper wall of the worktable 2 and is used to scrape off the cleaned objects on the upper wall of the worktable 2. A motor 106 is provided on the lower left side of the worktable 2. A screw 106a is fixed on the power output shaft of the motor 106. When the motor 106 works, it drives the screw 106a to rotate, which can ultimately drive the brush roller 102 and the scraper 103 to move and clean the cleaned objects on the upper wall of the worktable 2. Specifically, the brush roller 102 has a rectangular strip 112 with an internal clearance fit. The rear end of the rectangular strip 112 is fixed with a protrusion 112a. The protrusion 112a is fixedly connected to the power output shaft of the motor 101. When the motor 101 works, it drives the protrusion 112a to rotate, thereby causing the rectangular strip 112 to rotate, and finally causing the brush roller 102 to rotate. The brush roller 102 has side plates 107 symmetrically arranged at the front and rear. The motor 101 is fixedly connected to the side plate 107 located at the rear. The guide rail 104 has a guide groove 104a on the side wall away from the worktable 2, and the side plate 107 has a boss 107a fixed on the side wall near the worktable 2, which is located inside the guide groove 104a. The above configuration can provide the side plate 107 with a left and right direction moving guide function. A positioning sleeve 110 is provided with an internal clearance fit at the front end of the rectangular strip 112. The positioning sleeve 110 is clearance fit with the side plate 107 located on the front side. A bolt 110a is provided through the interior of the positioning sleeve 110. The positioning sleeve 110 is fixedly connected to the rectangular strip 112 by the bolt 110a. With the above configuration, by removing the bolt 110a, the positioning sleeve 110 can be separated from the rectangular strip 112 and the side plate 107 located on the front side. At this time, the side plate 107 located on the front side can be moved to the left, and the brush roller 102 can be moved forward to remove and replace the brush roller 102. An extension strip 111, fixed to the shovel plate 103, is provided on the side of the side plate 107 away from the workbench 2. A leak-proof plate 103a, fixed to the shovel plate 103, is provided on the side of the extension strip 111 near the workbench 2. The lower wall of the leak-proof plate 103a can contact the upper wall of the corresponding guide rail 104, which can prevent the dust on the upper wall of the workbench 2 from moving to the right and then leaking through both ends of the shovel plate 103 caused by the rotation of the brush roller 102. A positioning rod 111a is fixed to the left end of the front wall of the extension strip 111 located on the rear side. The positioning rod 111a is positioned between the left end of the front wall of the extension strip 111 located on the rear side and the side plate 107 located on the rear side. The left end of the extension strip 111 located on the front side is fixed with a ring 109. The internal thread of the ring 109 is connected to a bolt 109a. The rear end of the bolt 109a is a smooth cylindrical surface, and the rear end of the bolt 109a is in clearance fit with the side plate 107 located on the front side. With the above configuration, when the side plate 107 located on the front side is disassembled, the bolt 109a is disassembled from the ring 109, and the shovel plate 103 is moved back to disassemble the positioning rod 111a from the side plate 107 located on the rear side, so that the disassembly operation of the shovel plate 103 can be completed. The screw 106a is externally threaded with a connecting plate 105. The front and rear ends of the connecting plate 105 are respectively fixedly connected to the corresponding side plates 107. The left and right ends of the screw 106a are provided with end plates 108 fixed to the worktable 2. The screw 106a is rotatably connected to the end plates 108 through bearings. The motor 106 is fixedly connected to the end plate 108 located on the left side. With the above configuration, the screw 106a rotates to drive the connecting plate 105 to move, thereby causing the side plates 107 to move, thus driving the brush roller 102 and the shovel plate 103 to move. Furthermore, support legs are fixed at both ends of the lower wall of guide rail 104. The lower ends of the support legs are fixed on the mounting platform of the fully automatic dispensing machine. Meanwhile, motor 101 and motor 206 are electrically connected to the microcontroller in the controller through wires. The microcontroller in the controller is electrically connected to an external power supply through wires. Motor 101, motor 206 and the controller are all existing technologies and can be obtained through market purchase or private customization. Their models are not limited here. The operation process of this embodiment is as follows: When cleaning the upper wall of the workbench 2, the controller is used to make the motor 106 drive the screw 106a to rotate, which causes the connecting plate 105 to move the side plate 107 to the left, thereby causing the brush roller 102 and the scraper 103 to be located at the left end of the upper wall of the workbench 2. Then, the controller is used to make the motor 101 drive the rectangular bar 112 to rotate, which drives the brush roller 102 to rotate counterclockwise. The controller then controls the motor 106 to drive the screw 106a to rotate, which causes the connecting plate 105, the side plate 107, the brush roller 102 and the scraper 103 to move to the right. At this time, the scraper 103 performs the first cleaning of the upper wall of the workbench 2. Then, the brush roller 102 moves along the trajectory after the scraper 103 removes the cleaning material while rotating, so as to clean the workbench 2 again after the cleaning material is removed.

[0027] Example 2 Please see Figure 1 and Figure 7 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: the collection mechanism 3 includes a collection box 303 located below the right end of the workbench 2 for collecting the cleaned items. Vertical plates 302 are symmetrically arranged in front of and behind the collection box 303. A spring 304 is provided on the side of the vertical plate 302 away from the guide rail 104 for providing support to the rectangular plate 301, so that the collection box 303 is hidden below the right side of the workbench 2 under normal conditions. Specifically, rotating rods 303a are fixedly provided on the upper ends of the front and rear side walls of the collection box 303. The rotating rods 303a are rotatably connected to the corresponding vertical plates 302 through bearings. By flipping the collection box 303, the cleaned material inside the collection box 303 can be poured out. A boss 302a located inside the guide groove 104a is fixedly provided on the side wall of the vertical plate 302 near the collection box 303, so that the vertical plate 302 can move in the left and right directions along the guide rail 104. Rectangular plate 301 and rectangular plate 305 are fixedly mounted on the left and right ends of spring 304, respectively. Rectangular plate 301 and rectangular plate 305 are fixedly connected to the corresponding side plate 107 and guide rail 104. The operation process of this embodiment is as follows: When cleaning the upper wall of the workbench 2, the second motor 106 works to make the brush roller 102 and the shovel plate 103 move to the right until the side plate 107 moves to contact the vertical plate 302. Under the continuous operation of the second motor 106, the side plate 107 moves to the right and pushes the vertical plate 302 to the right, so that the right end of the collection box 303 extends out of the right end of the workbench 2. During this process, the cleaned items removed by the shovel plate 103 and the cleaned items cleaned by the rotation of the brush roller 102 fall into the inside of the collection box 303. Then the controller controls the second motor 106 to work, so that the brush roller 102 and the shovel plate 103 move to the left to the initial position to wait for the next cleaning. At this time, under the action of the spring 304, the rectangular plate 301 is pushed to the left, which drives the vertical plate 302 to the left, thereby driving the collection box 303 to the left and hide it under the right side of the workbench 2.
