Description

Technical Field

[0001] This utility model relates to the field of dispensing technology, specifically to a multi-head synchronous dispensing structure for an automatic dispensing machine. Background Technology

[0002] In the field of automated production, dispensing equipment is widely used in the precision processing of industries such as electronics, automotive parts, and medical devices. To improve dispensing efficiency, existing technologies often use two or more dispensing heads to perform dispensing on multiple points at once, thereby improving production efficiency.

[0003] However, when a workpiece needs to be glued to different parts (such as the front and back sides), existing equipment usually relies on manual operation to flip the workpiece. The operator must first loosen the clamps or limiting devices that fix the workpiece, manually flip the workpiece, and then readjust and fix the workpiece position for subsequent glue dispensing operations. The manual flipping method is not only cumbersome, requiring multiple disassembly and fixation of the workpiece, which consumes a lot of time and manpower, but also the repetitive manual operation is prone to workpiece positioning errors, affecting the glue dispensing accuracy and consistency. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing an automatic dispensing machine with a multi-head synchronous dispensing structure. This solves the problem that existing equipment usually relies on manual operation to flip the workpiece. Operators need to first loosen the clamps or limiting devices that fix the workpiece, manually flip the workpiece, and then readjust and fix the workpiece position for subsequent dispensing operations. The manual flipping method is not only cumbersome, but also requires multiple disassemblies and fixations of the workpiece, consuming a lot of time and manpower.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An automatic dispensing machine multi-head synchronous dispensing structure, comprising:

[0006] frame;

[0007] Two wall panels are arranged opposite to each other on the frame;

[0008] A two-axis robotic arm, comprising a z-axis and a y-axis, wherein the y-axis is mounted on a wall panel and the z-axis is mounted on the moving end of the y-axis;

[0009] The dispensing section includes two dispensing heads arranged side by side, wherein the two dispensing heads are disposed on the moving end of the z-axis;

[0010] A support block, the two ends of which are rotatably connected between the wall panels via rotating shafts, wherein the support block has an accommodating opening inside;

[0011] A main shaft, one end of which is fixed to one side of a bearing block, and the other end of which penetrates the wall panel;

[0012] The gear is sleeved on the outside of one end of the main shaft that passes through the wall panel;

[0013] A rack that meshes with the bottom of a gear;

[0014] An electric linear actuator is installed on one side of the wall panel, and the drive end of the electric linear actuator is connected to one end of the rack.

[0015] A limiting component is disposed within the receiving opening of the bearing block and is used to fix the workpiece within the receiving opening.

[0016] The beneficial effects of this utility model are:

[0017] 1) The workpiece is securely fixed within the receiving opening of the support block using a limiting component. An electric push rod drives the rack and pinion mechanism, which meshes with the gears to rotate the main shaft and support block, thus automatically flipping the workpiece and completing the dispensing operation on both sides. Compared to existing technologies, this dispensing structure automates workpiece flipping, eliminating the tedious steps of manual loosening, flipping, and re-fixing, significantly improving dispensing efficiency. Secondly, the precise design of the gear-rack transmission and limiting component ensures positioning accuracy during workpiece flipping, avoiding deviations that may occur during manual operation, thereby guaranteeing dispensing quality. Thirdly, its compact design and simple operation make it suitable for various workpiece sizes and dispensing needs, effectively improving the overall efficiency and stability of automated production lines and meeting the high-efficiency and high-precision requirements of modern industrial production.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, the dispensing unit also includes a support member, a bidirectional threaded screw, a fixing plate, a guide rail, a handwheel, two nuts, and two sliders, with the support member fixed on the moving end of the z-axis.

[0020] Furthermore, the guide rail is fixed to the support member, the fixing plate is fixed to both ends of the guide rail, and the two ends of the bidirectional threaded screw are rotatably connected between the fixing plates via a rotating shaft.

[0021] Furthermore, the two sliders slide outside the guide rail, the two nuts are screwed onto the outside of the bidirectional threaded screw, and the handwheel is fixed to one end of the bidirectional threaded screw.

[0022] Furthermore, one side of each dispensing head is sequentially fixed to a slider and a nut.

[0023] The beneficial effect of adopting the above-mentioned further solution is that by rotating the handwheel, the bidirectional threaded screw rotates accordingly. Since the bidirectional threaded screw has threads in opposite directions, the two nuts move in opposite directions when the screw rotates, and drive the dispensing head and the slider to move in opposite directions on the guide rail, thereby achieving precise adjustment of the distance between the two dispensing heads to adapt to the position requirements of different dispensing points on the workpiece.

[0024] Furthermore, the limiting component includes a fastening bolt, and one end of the fastening bolt is threaded onto one side of the bearing block. Attached Figure Description

Detailed Implementation

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] In the field of automated production, dispensing equipment is widely used in the precision processing of industries such as electronics, automotive parts, and medical devices. To improve dispensing efficiency, existing technologies often use two or more dispensing heads to perform dispensing on multiple points at once, thereby improving production efficiency.

[0033] However, when a workpiece needs to be glued to different parts (such as the front and back sides), existing equipment usually relies on manual operation to flip the workpiece. The operator must first loosen the clamps or limiting devices that fix the workpiece, manually flip the workpiece, and then readjust and fix the workpiece position for subsequent glue dispensing. The manual flipping method is not only cumbersome, requiring multiple disassembly and fixation of the workpiece, which consumes a lot of time and manpower, but also the repetitive manual operation is prone to workpiece positioning errors, affecting the glue dispensing accuracy and consistency. In response, the inventor has proposed an automatic glue dispensing machine with a multi-head synchronous glue dispensing structure to solve the above problems.

[0034] The present invention provides the following preferred embodiments.

[0035] like Figures 1-4 As shown, an automatic dispensing machine multi-head synchronous dispensing structure includes:

[0036] Rack 1;

[0037] Two wall panels 2 are arranged opposite to each other on the frame 1;

[0038] The two-axis robotic arm 3 includes a z-axis 302 and a y-axis 301, wherein the y-axis 301 is mounted on the wall panel 2, and the z-axis 302 is mounted on the moving end of the y-axis 301.

[0039] The dispensing unit 4 includes two dispensing heads 401 arranged side by side, wherein the two dispensing heads 401 are disposed on the moving end of the z-axis 302.

[0040] The bearing block 5 has two ends that are rotatably connected to the wall panel 2 via a rotating shaft. The bearing block 5 has an opening 11 inside.

[0041] Main shaft 6, one end of which is fixed to one side of the bearing block 5, and the other end of which penetrates the wall panel 2;

[0042] Gear 7 is sleeved on the outside of one end of the main shaft 6 that passes through the wall plate 2;

[0043] Rack 8 meshes with the bottom of gear 7;

[0044] Electric linear actuator 9 is installed on one side of wall panel 2, and the drive end of electric linear actuator 9 is connected to one end of rack 8.

[0045] Limiting component 10 is disposed in the receiving opening 11 of the bearing block 5 and is used to fix the workpiece in the receiving opening 11.

[0046] The workpiece is securely fixed within the receiving opening 11 of the support block 5 using the limiting component 10. The rack 8 is displaced by the electric push rod 9, and the rack 8 meshes with the gear 7, driving the main shaft 6 and the support block 5 to rotate, thus achieving automatic workpiece flipping and completing the dispensing operation on both sides of the workpiece. Compared to existing technologies, this dispensing structure automates workpiece flipping, eliminating the tedious steps of manual loosening, flipping, and re-fixing, significantly improving dispensing efficiency. Secondly, the precise design of the gear 7-rack 8 transmission and the limiting component 10 ensures positioning accuracy during workpiece flipping, avoiding deviations that may occur during manual operation, thereby guaranteeing dispensing quality. Thirdly, the structure is compact, easy to operate, and suitable for various workpiece sizes and dispensing needs, effectively improving the overall efficiency and stability of automated production lines and meeting the high-efficiency and high-precision requirements of modern industrial production.

[0047] In this embodiment, as Figures 1-4 As shown, the dispensing unit 4 also includes a support 402, a bidirectional threaded screw 408, a fixing plate 407, a guide rail 403, a handwheel 404, two nuts 405, and two sliders 406. The support 402 is fixed on the moving end of the z-axis 302, the guide rail 403 is fixed on the support 402, the fixing plate 407 is fixed on both ends of the guide rail 403, the two ends of the bidirectional threaded screw 408 are rotatably connected between the fixing plate 407 through a rotating shaft, the two sliders 406 slide on the outside of the guide rail 403 respectively, the two nuts 405 are screwed on the outside of the bidirectional threaded screw 408, the handwheel 404 is fixed on one end of the bidirectional threaded screw 408, and one side of each dispensing head 401 is fixed to a slider 406 and a nut 405 in sequence.

[0048] By rotating the handwheel 404, the bidirectional threaded screw 408 rotates accordingly. Since the bidirectional threaded screw 408 has threads in opposite directions, the two nuts 405 move in opposite directions when the screw rotates, and drive the dispensing head 401 and the slider 406 to move in opposite directions on the guide rail 403, thereby achieving precise adjustment of the distance between the two dispensing heads 401 to adapt to the position requirements of different dispensing points on the workpiece.

[0049] In this embodiment, as Figures 1-4 As shown, the limiting component 10 includes a fastening bolt, and one end of the fastening bolt is threaded onto one side of the bearing block 5.

[0050] The specific working process of this utility model is as follows:

[0051] First, place the workpiece into the receiving opening 11 of the bearing block 5, and then tighten the fastening bolt to make the fastening bolt press against the workpiece to fix the workpiece. When it is necessary to flip the workpiece for dispensing, the electric push rod 9 drives the rack 8 to move. The rack 8 meshes with the gear 7 to drive the main shaft 6 and the bearing block 5 to rotate, so as to realize the automatic flipping of the workpiece and complete the dispensing operation on both sides of the workpiece.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
