Description

[0001] The utility model relates to the technical field of dispensing equipment, in particular to a dispenser. Background Art

[0002] A dispenser is a process equipment widely used in the field of electronic product production, and its use processes include bonding, potting, coating, sealing, filling, dropping, scribing and dispensing, etc.

[0003] Among them, a dispensing valve is the core component of a dispenser. The jet dispensing valve can achieve high-speed non-contact dispensing and can reach a relatively fast dispensing speed. In order to improve the dispensing efficiency, a synchronous double-dispensing valve is used for the dispensing process. The double-dispensing valve means that two identical dispensing valves perform synchronous dispensing in the same way on a synchronous rack. In the existing synchronous double-dispensing valve technology, the distance between the main dispensing valve and the auxiliary dispensing valve is generally fixed, or the distance between the main dispensing valve and the auxiliary dispensing valve can be finely adjusted during the working process.

[0004] However, when the electronic product changes the production line, that is, different sizes of products are replaced for processing, the corresponding dispensing process also needs to be changed. At this time, the distance between the main dispensing valve and the auxiliary dispensing valve needs to be changed accordingly. In this case, the distance between the original main dispensing valve and the auxiliary dispensing valve is often adjusted manually. However, generally, the dispensing process requires high precision. When manually adjusting the distance between the main dispensing valve and the auxiliary dispensing valve, it takes a long time, resulting in a decrease in the dispensing efficiency.

In addition, the terms "first", "second" etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0039] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 which is a schematic structural diagram of a dispensing machine provided by an embodiment of the present utility model; Figure 2 is Figure 1Schematic structural diagram of the dispensing machine at the first angle; Figure 3 is Figure 1 Schematic structural diagram of the dispensing machine at the second angle.

[0041] The dispensing machine 100 provided by an embodiment of the present utility model includes a valve seat mechanism 10, a main dispensing valve 20, a sub-dispensing valve 30, a first adjustment assembly 40, a control device, and a camera assembly 50. The valve seat mechanism 10 includes a first valve seat 11, a second valve seat 12, and a first guide rail 13. The first valve seat 11 is connected to the second valve seat 12. The second valve seat 12 includes an adjustment slot 121. The first guide rail 13 is connected to the second valve seat 12 and is located on one side of the second valve seat 12. The length direction of the first guide rail 13 is the same as the arrangement direction of the first valve seat 11 and the second valve seat 12. The main dispensing valve 20 is connected to the first valve seat 11. The sub-dispensing valve 30 is slidably connected to the first guide rail 13. The first adjustment assembly 40 is connected to the sub-dispensing valve 30, and the first adjustment assembly 40 is received in the adjustment slot 121. The control device is communicatively connected to the first adjustment assembly 40. The camera assembly 50 is connected to the first valve seat 11, and the camera assembly 50 is communicatively connected to the control device. The camera assembly 50 can photograph the dispensing process of the main dispensing valve 20 and the sub-dispensing valve 30. The control device can control the first adjustment assembly 40 to drive the sub-dispensing valve 30 to slide along the first guide rail 13 according to the photographing result of the camera assembly 50, so as to adjust the distance between the main dispensing valve 20 and the sub-dispensing valve 30.

[0042] Here, it should be noted that during the operation of the dispensing machine 100, the main dispensing valve 20 and the sub-dispensing valve 30 can operate simultaneously. Moreover, during the operation of the dispensing machine 100, the object to be dispensed can be roughly regarded as a matrix formed by multiple points. The main dispensing valve 20 and the sub-dispensing valve 30 can perform simultaneous dispensing operations on two points within the matrix by controlling the distance between the main dispensing valve 20 and the sub-dispensing valve 30. When the object to be dispensed changes, that is, when the dispensing product is replaced, the distance within the corresponding dispensing matrix will also change, and the distance between the corresponding main dispensing valve 20 and the sub-dispensing valve 30 also needs to be adjusted accordingly.

[0043] For example, taking the main dispensing valve 20 as the initial fixed point, the first adjustment component 40 controls the secondary dispensing valve 30 to slide along the first guide rail 13 to adjust the relative position between the secondary dispensing valve 30 and the main dispensing valve 20. In other words, the distance between the main dispensing valve 20 and the secondary dispensing valve 30 in the length direction of the first guide rail 13 is adjusted to adapt to the processing scenario. Specifically, the main dispensing valve 20 and the secondary dispensing valve 30 first perform the first dispensing proofing. The imaging component 50 takes pictures based on the results of the first dispensing proofing, and the control device analyzes the photographed results to check whether the dispensing positions of the main dispensing valve 20 and the secondary dispensing valve 30 match the product requirements. If not, the control device controls the first adjustment component 40 to drive the secondary dispensing valve 30 to slide along the first guide rail 13 to adjust the relative position between the main dispensing valve 20 and the secondary dispensing valve 30 to meet the dispensing product requirements; thus avoiding the errors caused by manual adjustment. This adjustment method improves the replacement dispensing efficiency of the dispenser 100 and can also improve the dispensing quality of the dispenser 100.

[0044] In addition, the first adjustment component 40 can be implemented through various structures, and does not specifically refer to a certain structure. For example: stepper motor and lead screw; ball screw and screw motor; electric push rod and electric cylinder, etc.

[0045] In this embodiment, both the main dispensing valve 20 and the secondary dispensing valve 30 are located on the same side of the first guide rail 13. For the convenience of understanding, here, the arrangement direction of the main dispensing valve 20 and the secondary dispensing valve 30 is set as the X-axis direction, the length direction of the first guide rail 13 is set along the X-axis direction, and the first adjustment component 40 can drive the secondary dispensing valve 30 to approach or move away from the main dispensing valve 20 along the X-axis direction.

[0046] Refer to Figure 3 、 Figure 4 and Figure 5 , Figure 4 is Figure 3 the enlarged structural schematic diagram of part A of the dispenser in Figure 5 is Figure 1 the partial structural schematic diagram of the first adjustment component, the second adjustment component and the secondary dispensing valve in the dispenser.

[0047] In one embodiment, the dispenser 100 further includes a linkage assembly 60 and a second adjustment assembly 70. The linkage assembly 60 includes a connection plate 61 and a second guide rail 62. One side of the connection plate 61 is slidably connected to the first guide rail 13, and the second guide rail 62 is connected to the other side of the connection plate 61. The secondary dispensing valve 30 is slidably connected to the second guide rail 62. Both the primary dispensing valve 20 and the secondary dispensing valve 30 are located on the same side of the first guide rail 13. The length direction of the second guide rail 62 is perpendicular to the length direction of the first guide rail 13, and the length direction of the second guide rail 62 is consistent with the arrangement direction from the secondary dispensing valve 30 to the second valve seat 12. The second adjustment assembly 70 is connected to the connection plate 61 and is also connected to the secondary dispensing valve 30. The control device is communicatively connected to the second adjustment assembly 70, and the control device can control the second adjustment assembly 70 to drive the secondary dispensing valve 30 to slide along the second guide rail 62.

[0048] Specifically, the secondary dispensing valve 30 is slidably connected to the first guide rail 13 through the connection plate 61, and the secondary dispensing valve 30 is also slidably connected to the second guide rail 62. During actual operation, the control device analyzes the photographing results of the imaging assembly 50 and controls the second adjustment assembly 70 to drive the secondary dispensing valve 30 to slide along the second guide rail 62 according to the analysis results, so that the secondary dispensing valve 30 and the primary dispensing valve 20 are on the same straight line. Then, the secondary dispensing valve 30 drives the connection plate 61 and the secondary dispensing valve 30 through the first adjustment assembly 40 to adjust the distance between the secondary dispensing valve 30 and the primary dispensing valve 20, thus completing the adjustment of the distance between the secondary dispensing valve 30 and the primary dispensing valve 20.

[0049] It should be noted that the length direction of the second guide rail 62 is perpendicular to the length direction of the first guide rail 13. For ease of understanding, the length direction of the first guide rail 13 is set as the X-axis, and the length direction of the second guide rail 62 is set as the Y-axis direction. The X-axis direction and the Y-axis direction are perpendicular to each other in a plane. The second adjustment assembly 70 can drive the secondary dispensing valve 30 to move along the Y-axis direction to ensure that the secondary dispensing valve 30 and the primary dispensing valve 20 are on the same straight line in the X-axis direction.

[0050] Furthermore, in the dispensing matrix, two adjacent dispensing points can be regarded as point A and point B. When the product line is changed, the relative positions of point A and point B change, that is, point A and point B will have position changes on the X-axis and the Y-axis. Regarding the point dispensed by the primary dispensing valve 20 as point A and the point dispensed by the secondary dispensing valve 30 as point B, the position of point B on the X-axis is adjusted through the first adjustment assembly 40, and the position of point B on the Y-axis is adjusted through the second adjustment assembly 70, so that the relative positions of point A and point B fit the position relationship after the product line is changed. That is, such a setting can improve the dispensing adaptability of the dispenser 100, avoid the time for disassembling and reassembling the secondary dispensing valve 30 after the product line is changed, and improve the dispensing efficiency.

[0051] Refer to Figure 5 、Figure 6 and Figure 7 , Figure 5 is Figure 1 Partial structural schematic diagrams of the first adjustment component, the second adjustment component and the auxiliary dispensing valve in the dispensing machine; Figure 6 is Figure 1 Structural schematic diagram of the second valve seat of the dispensing machine; Figure 7 is Figure 1 Structural schematic diagram of the second valve seat and the connecting block of the dispensing machine from another angle.

[0052] In one embodiment, the second valve seat 12 includes a first side wall 122, a second side wall 123, a third side wall 124 and a fourth side wall 125. The second side wall 123 is connected between the first side wall 122 and the third side wall 124. The first side wall 122, the second side wall 123 and the third side wall 124 enclose an adjustment groove 121. The fourth side wall 125 is located in the adjustment groove 121. The fourth side wall 125 is connected between the first side wall 122 and the third side wall 124. The fourth side wall 125 divides the adjustment groove 121 into a first chamber 1211 and a second chamber 1212. The arrangement direction from the first chamber 1211 to the second chamber 1212 is the same as the arrangement direction from the second valve seat 12 to the first valve seat 11. The first adjustment component 40 includes a first adjustment motor 41, a first lead screw 42 and a first connecting block 43. The first adjustment motor 41 is received in the first chamber 1211. An installation opening 1251 is formed on the fourth side wall 125. One end of the first lead screw 42 is connected to the output end of the first adjustment motor 41. The first lead screw 42 passes through the installation opening 1251 and penetrates the second chamber 1212. The other end of the first lead screw 42 is installed on the second side wall 123. The first connecting block 43 is threadedly connected to the first lead screw 42. The first connecting block 43 is connected to the connecting plate 61.

[0053] Specifically, the adjustment groove 121 is generally a U-shaped groove. The notch of the adjustment groove 121 faces away from the first valve seat 11 to facilitate the installation of the first adjustment motor 41. By providing the fourth side wall 125 to divide the adjustment groove 121 into the first chamber 1211 and the second chamber 1212, the first chamber 1211 is used for placing the first adjustment motor 41, and the second chamber 1212 is used for placing the first lead screw 42 and the first connecting block 43. During the actual installation process, first place the first adjustment motor 41 into the first chamber 1211, and then place the first lead screw 42 close to the side wall of the installation opening 1251 to achieve the purpose of quick installation. In addition, the specific movement of the first connecting block 43 can be observed through the upper opening of the adjustment groove 121.

[0054] Furthermore, in this embodiment, the second valve seat 12 also includes a bottom plate 126, the first side wall 122, the second side wall 123, the third side wall 124 and the fourth side wall 125 are all connected to the bottom plate 126 and are all located above the bottom plate 126, the first guide rail 13 is installed on the side of the bottom plate 126 away from the adjustment groove 121, and a connecting port 1261 is opened on the bottom plate 126, and the first connecting block 43 passes through the connecting port 1261 and is connected to the connecting plate 61.

[0055] The first adjusting motor 41 can be a stepping motor. The output end of the first adjusting motor 41 can drive the first lead screw 42 to rotate. As the first lead screw 42 rotates, the first connecting block 43 moves back and forth along the surface of the first lead screw 42. The first connecting block 43 drives the connecting plate 61 to move along the first guide rail 13, that is, the connecting plate 61 drives the auxiliary dispensing valve 30 and the second adjusting component 70 to move in the X-axis direction.

[0056] It should be noted that the length of the first lead screw 42 is set according to the length of the second chamber 1212 .

[0057] In one embodiment, the first adjustment component 40 further includes a first sensor 44 , which is mounted on the fourth side wall 125 . The first sensor 44 is in communication with the control device, and the first sensor 44 can feed back position information of the first connection block 43 to the control device.

[0058] Specifically, the first sensor 44 is installed on the fourth side wall 125 to make the overall dispensing machine structure more compact. The first sensor 44 is used to feed back the position information of the first connecting block 43 to the control device, so that the control device controls the first adjustment motor 41 to adjust the position of the first connecting block 43, thereby achieving the purpose of accurately adjusting the position of the auxiliary dispensing valve 30.

[0059] The first sensor 44 may be a laser distance measuring sensor or a photoelectric sensor. In practical applications, the corresponding sensor may be replaced according to specific needs.

[0060] In this embodiment, the first sensor 44 is a photoelectric sensor. Specifically, a baffle is provided on the first connecting block 43. The baffle is located between the light source transmitter and the light source receiver on the photoelectric sensor, and this position is recorded as the initial position. When the control device needs to adjust the auxiliary dispensing valve 30, the control device controls the first adjustment motor 41 to rotate according to the analysis result, and the corresponding baffle will be separated from the light source transmitter and the light source receiver. If the baffle is not separated from the photoelectric sensor, an optical signal can be sent to report an error.

[0062] In one embodiment, the second adjustment component 70 also includes a second adjustment motor 71, a second lead screw 72 and a second connecting block 73. The second adjustment motor 71 is connected to the connecting plate 61, the output end of the second adjustment motor 71 is connected to the second lead screw 72, the second connecting block 73 is threadedly connected to the second lead screw 72, and the second connecting block 73 is connected to the auxiliary dispensing valve 30.

[0063] Specifically, the first adjusting motor 41 and the second adjusting motor 71 may be the same stepping motor, and the first lead screw 42 and the second lead screw 72 may be the same lead screw, that is, they may be purchased at the same time during the procurement process to reduce costs.

[0064] In one embodiment, the second adjustment component 70 further includes a second sensor 74, which is installed on one side of the connecting plate 61. The second sensor 74 is communicatively connected to the control device, and the second sensor 74 can feed back position information of the second connecting block 73 to the control device.

[0065] Specifically, the second sensor 74 is mounted on the connecting plate 61 and is located on a side of the connecting plate 61 away from the first valve seat 11 , so that the structure of the second regulating assembly 70 is more compact.

[0066] In this embodiment, the second sensor 74 and the first sensor 44 both use photoelectric sensors and have the same principle, which will not be elaborated here; the purpose of the first sensor 44 and the second sensor 74 also using photoelectric sensors is to reduce procurement costs, that is, to reduce the cost of the dispensing machine 100.

[0067] See also Figure 10 , Figure 10 yes Figure 1 Schematic diagram of the structure of the center dispensing machine from the fourth angle.

[0068] In one embodiment, the first valve seat 11 includes a slide groove 111, the length direction of the slide groove 111 is perpendicular to the length direction of the first guide rail 13, and the length direction of the slide groove 111 is also perpendicular to the length direction of the second guide rail 62. The camera assembly 50 includes a camera 51 and a slider 52. The camera 51 is connected to the slider 52, and the slider 52 is slidably connected to the first valve seat 11 along the groove wall of the slide groove 111.

[0069] Specifically, when replacing the dispensing product, the focusing position of the camera 51 may change. By sliding the slider 52 along the chute 111, the focusing position of the camera 51 is made to fit the replaced dispensing product, so as to ensure that the image taken by the camera 51 is clear. In this embodiment, a threaded hole is provided on the slider 52. When the slider 52 moves to the specified position, the slider 52 is fixed on the chute 111 by a screw passing through the threaded hole, so as to ensure that the focusing position of the camera 51 remains unchanged.

[0076] Specifically, the third adjustment component 80 adopts a differential head structure in actual application. When there is a height difference between the main dispensing valve body 22 and the auxiliary dispensing valve body 32, the screw 82 is driven to rotate by rotating the shaft sleeve 81, thereby driving the linkage block 83 to move up and down along the screw 82. The linkage block 83 drives the first mounting block 21 to move up and down along the third guide rail 115 to adjust the horizontal height of the main dispensing valve body 22, thereby ensuring that the main dispensing valve body 22 and the auxiliary dispensing valve body 32 are at the same horizontal height.
