[0073] The present utility model provides a dispensing machine 100. Specifically, please refer to Figures 1 to 3 , in this embodiment, the dispensing machine 100 includes a frame 1, a conveying assembly 6, a dispensing assembly 2, a weighing assembly 3, and a position detection assembly 4. A dispensing station is provided on the frame 1. The frame is provided with a feeding port and a discharging port on opposite sides along its transverse direction.

The weighing assembly 3 can be used to weigh the single-time dispensing weight of the dispensing assembly 2. The position detection assembly 4 is disposed on the frame 1 and is used to measure the height of the glue outlet 2212 of the dispensing assembly 2.

[0074] In this embodiment, by movably arranging the dispensing assembly 2 on the machine frame 1, the dispensing assembly 2 can move flexibly for dispensing; through the weighing assembly 3, the single-time dispensing weight of the dispensing assembly 2 can be obtained. Before each dispensing of the dispensing assembly 2, the single-time dispensing amount of the dispensing assembly 2 can be weighed first, so as to judge whether the dispensing amount is appropriate, and the accuracy of the dispensing amount can be ensured when the dispensing assembly 2 is dispensing. Or during the dispensing process of the dispensing assembly 2, after an interval of a certain period of time, the dispensing assembly 2 can move to the weighing assembly 3 to verify the single-time dispensing amount of the dispensing assembly 2 again, so that it can be ensured that the dispensing amount of the dispenser 100 is always within the preset dispensing range during the dispensing process; moreover, a position detection assembly 4 is also provided. Through the position detection assembly 4, the height of the dispensing port of the dispensing assembly 2 can be measured to ensure that when dispensing different products, the dispensing port of the dispensing assembly 2 can be at a height suitable for different products; and a transfer assembly 6 is also provided. Through the transfer assembly 6, the automatic transfer of products is realized, making the dispensing process of the dispenser 100 more automated, the operation more convenient, the working efficiency higher, and the dispensing effect of the dispenser 100 better ensured.

[0075] In one embodiment, the dispenser 100 further includes a control device, which is electrically connected to the weighing assembly 3, the position detection assembly 4, and the dispensing assembly 2. The control device can adjust the glue output amount of the dispensing assembly 2 according to the weight value weighed by the weighing assembly 3, and can adjust the height of the glue outlet 2212 according to the detection result of the position detection assembly 4.

[0076] Among them, in combination with Figure 2 、 Figure 9 and Figure 10 as shown, the machine frame 1 includes a support bottom plate 11, a support top plate 12 and a support structure 13. The support bottom plate 11 and the support top plate 12 are arranged at a relative interval in the up and down direction. The support structure 13 connects the support bottom plate 11 and the support top plate 12 and is supported between the support bottom plate 11 and the support top plate 12; among them, the support structure 13 forms a plurality of support cavities, each support cavity is hollow with both ends open, and the plurality of support cavities are arranged in a ring shape, so that the support bottom plate 11 and the support top plate 12 respectively cover the two open ends of the plurality of support cavities. The dispensing assembly 2 and the weighing assembly 3 are both arranged on the support top plate 12.

[0077] In this embodiment, the bottom support is formed by the support bottom plate 11, and the dispensing assembly 2 and other structures can be arranged on the support top plate 12 through the support top plate 12 to support the dispensing assembly 2 at a certain height; moreover, the support structure 13 forms a support between the support bottom plate 11 and the support top plate 12, so that the stability of the support top plate 12 is better; furthermore, through the support structure 13, a plurality of support cavities are formed, each support cavity is hollow, and both ends of the opening are closed by the support bottom plate 11 and the support top plate 12. The annular support cavity can make the support strength better, and there are a plurality of support cavities, which can better ensure the stability of the support top plate 12. It is not easy for the support bottom plate 11 and the support top plate 12 to shake relatively, with high strength and good stability, so that the dispensing assembly 2 is more stable during operation, the dispensing accuracy is higher, and the dispensing effect is better.

[0078] Among them, as Figure 9 shown in, the support bottom plate 11 and the support top plate 12 are both arranged in a substantially flat plate shape and are both substantially square, so as to have a long side and a short side. Preferably, the shape of the support bottom plate 11 is the same as the shape of the support top plate 12. It should be noted that when the rack 1 is in normal use, the length direction of the support bottom plate 11 and the length direction of the support top plate 12 can be arranged horizontally, then the width direction of the support bottom plate 11 and the width direction of the support top plate 12 are arranged vertically. Specifically, when the length direction of the support bottom plate 11 and the length direction of the support top plate 12 are arranged in the left-right direction, the width direction of the support bottom plate 11 and the width direction of the support top plate 12 are arranged in the front-back direction. In the present invention, the description of the orientation can be referred to accordingly without special instructions.

[0079] Preferably, the support bottom plate 11, the support top plate 12 and the support structure 13 are all made of metal material, and further preferably, they can be made of steel, so that the strength is better.

[0080] Among them, in combination with Figure 9 and Figure 10As shown, the support structure 13 includes two first support plates 131 arranged at relatively spaced intervals in the transverse direction, and two second support plates 132 provided on each of the first support plates 131. The two second support plates 132 are respectively located at both longitudinal ends of each of the first support plates 131. Among them, each of the second support plates 132 is bent and jointly encloses the support cavity with the first support plate 131. Each of the first support plates 131 extends along the length direction of the support bottom plate 11, and the two first support plates 131 are arranged to surround the opposite sides of the support bottom plate 11 or the support top plate 12 in the width direction, so as to form an installation space between the support bottom plate 11, the support top plate 12 and the two first support plates 131. Other components (such as a driving motor, a control device or a heat dissipation device, etc.) can be installed in this installation space, making the structure more compact. Each of the second support plates 132 and the first support plate 131 jointly enclose a support cavity, so that it is supported between the support bottom plate 11 and the support top plate 12 through a ring-shaped hollow structure, making the support area formed by the support structure 13 larger and the weight lighter.

[0081] Preferably, as Figure 10 shown, there are four second support plates 132. One second support plate 132 is connected to each of the two longitudinal ends of each first support plate 131. The four second support plates 132 can support at the four corners of the support bottom plate 11 and the support top plate 12 to ensure the support stability.

[0082] Furthermore, in combination with Figure 9 and Figure 10As shown, each of the first support plates 131 includes a first plate body 1311 and two first flanges 1312 respectively provided at both longitudinal ends thereof. Preferably, the two first flanges 1312 and the first plate body 1311 are integrally formed. During processing, the two first flanges 1312 are formed by bending both ends of the first support plate 131 along the length direction. The first plate body 1311 and the two first flanges 1312 are arranged in a substantially "U" shape. Each of the second support plates 132 includes a second plate body 1321, two support side plates 1322 respectively provided at both longitudinal ends thereof, and a second flange 1323 located at the end of one of the support side plates 1322. Preferably, the second plate body 1321, the two support side plates 1322 and the second flange 1323 are integrally bent. A "U" shape is formed between the second plate body 1321 and the two support side plates 1322. Among them, the second flange 1323 is connected to the first plate body 1311, and the support side plate 1322 without the second flange 1323 is connected to one of the first flanges 1312. By connecting one of the support side plates 1322 to one of the first flanges 1312 and connecting the second flange 1323 to the first plate body 1311, a support cavity substantially in a square shape is enclosed, so that each connection has a sufficient connection area, ensuring more reliable connection and thus greater stability.

[0083] Preferably, each of the first support plates 131 and each of the second support plates 132 are connected by riveting. Specifically, the connection between the second flange 1323 and the first plate body 1311 is connected by a riveting process, and the connection between the support side plate 1322 and the first flange 1312 is connected by a riveting process. The riveting process can make the rigidity of the entire frame 1 better and the connection accuracy higher.

[0084] Furthermore, as Figure 3 shown in, the frame 1 further includes a plurality of reinforcing plates 14. The plurality of reinforcing plates 14 are respectively provided in a plurality of the support cavities. Each of the reinforcing plates 14 supports between the two inner walls of the support cavities arranged oppositely. By the plurality of reinforcing plates 14, the inner sides of the support cavities are supported, so that the structural strength of each of the support cavities is better and each of the support cavities is not easily concave and deformed.

[0085] Preferably, two reinforcing plates 14 are provided in each of the support cavities, and the two reinforcing plates 14 are arranged in parallel at intervals. Of course, the number of the reinforcing plates 14 can be set according to the specific size of the support cavity to ensure that the strength of each part of the support cavity is more balanced, so that the phenomenon of local support collapse is not easily occurred, and the structural strength of the entire frame 1 is better.

[0086] Moreover, preferably, as Figure 9 shown, in the up-and-down direction, each of the reinforcing plates 14 is inclined. And the inclination directions of the reinforcing plates 14 at both ends of the same first plate body 1311 in the length direction are opposite to each other, so that the length of each of the reinforcing plates 14 can be set longer and the support is more stable.

[0087] It can be understood that through the support structure 13, the circumferential side and the four corners between the support bottom plate 11 and the support top plate 12 can all be stably supported. Specifically, in combination with Figure 3 and Figure 4 shown, the frame 1 further includes a plurality of reinforcing bars 15. The plurality of reinforcing bars 15 are respectively arranged on the support bottom plate 11 and the support top plate 12, and are respectively connected between every two adjacent second support plates 132. And at least two of the plurality of reinforcing bars 15 are arranged in a cross shape. A set of the reinforcing bars 15 arranged in a cross shape is arranged on the support bottom plate 11, and another set of the reinforcing bars 15 arranged in a cross shape is arranged on the support top plate 12. The plurality of reinforcing bars 15 are connected to support the middle of the support bottom plate 11 and the middle of the support top plate 12, so that the middle regions of the support bottom plate 11 and the support top plate 12 are supported by the reinforcing bars 15, and the plurality of support cavities are connected by the plurality of reinforcing bars 15. Each structure can be interconnected with each other, so that the overall strength is better.

[0088] In an embodiment, in combination with Figure 10 and Figure 11 shown, the frame 1 further includes a partition cavity 16. The partition cavity 16 connects the support bottom plate 11 and the support top plate 12 and extends horizontally. The two ends of the partition cavity 16 in the horizontal direction are respectively connected to two second support plates 132 that are opposite to each other in the horizontal direction. The partition cavity 16 divides the space between the support bottom plate 11 and the support top plate 12 into a first cavity and a second cavity in the longitudinal direction. The installation space inside the frame 1 is divided by the partition cavity 16 to be more suitable for different components to be installed in different cavities.

[0089] Specifically, as Figure 11 shown, the partition cavity 16 includes a box-shaped isolation cavity 161 and a cover plate 162 covering the cavity opening of the isolation cavity 161. The two ends of the cover plate 162 are arranged outside the support side plate 1322 and are connected to the first plate body 1311. The isolation cavity 161 is connected to the cover plate 162. A plurality of reinforcing plates 14 are also arranged in the partition cavity 16 to make the strength of the partition cavity 16 better.

[0090] Among them, the volume of the first cavity is larger than that of the second cavity, and each of the first plate bodies 1311 is provided with a hollowed-out area in the area corresponding to the first cavity. The first cavity can be used for installing a host or a control device, etc. A fan 244 can be correspondingly arranged in the hollowed-out area, and the heat in the first cavity can be quickly discharged through the fan 244, making the heat dissipation effect better.

[0091] For the dispensing assembly 2, it is mainly used for spraying glue to drop the glue onto the product, facilitating the subsequent bonding operation of the product. Specifically, in combination with Figure 2 and Figure 4 as shown, the dispensing assembly 2 includes a support frame 21, a valve body structure 22 and a glue storage cylinder 23. The support frame 21 is movably arranged on the frame 1 and has at least a moving stroke in the up-and-down direction of the frame 1 and the lateral direction of the frame 1; the valve body structure 22 is arranged on the support frame 21 and can move together with the support frame 21; the glue storage cylinder 23 is arranged on one side of the valve body structure 22 and is communicated with the valve body structure 22; the glue outlet 2212 is arranged at the bottom of the valve body structure 22, and the glue flowing out of the glue storage cylinder 23 can flow to the glue outlet 2212 and can be ejected out of the glue outlet 2212 under the action of the valve body structure 22. Since glue generally has a certain viscosity, it generally cannot flow out of the glue outlet 2212 under the action of its own gravity. Therefore, the valve body structure 22 can be used to push against the glue to control the amount of glue flowing out at the glue outlet 2212.

[0092] Among them, in combination with Figure 4 and Figure 5As shown, the support frame 21 includes a support plate 211, a first mounting block 212, and a second mounting block 213; the support plate 211 is arranged in a substantially square flat plate shape, and the length direction of the support plate 211 extends along the up-and-down direction of the frame 1; the first mounting block 212 is arranged on the support plate 211. Specifically, the first mounting block 212 can be fixedly mounted on the support plate 211 by a plurality of screws to ensure the stability of the connection, so that the valve body structure 22 and the glue storage cylinder 23 are not easily shaken; the second mounting block 213 is connected to the first mounting block 212, and the valve body structure 22 is connected to the second mounting block 213; wherein, an installation groove 2121 extending along the up-and-down direction of the frame 1 is provided on the first mounting block 212, and at least one end of the installation groove 2121 along the up-and-down direction of the frame 1 is open, and the second mounting block 213 can be slidably sleeved in the installation groove 2121 from the open end of the installation groove 2121. The second mounting block 213 is detachably mounted on the first mounting block 212, which is convenient for the disassembly and assembly of the second mounting block 213, thereby facilitating the disassembly, assembly and maintenance of the valve body structure 22 and the glue storage cylinder 23, and also making the assembly of the valve body assembly and the glue storage cylinder 23 more convenient.

[0093] Specifically, as Figure 5 shown in, the installation groove 2121 is a dovetail groove and is open at both ends along the up-and-down direction, and a plurality of convex columns are provided on the open side of the bottom of the installation groove 2121. The second mounting block 213 can be inserted into the installation groove 2121 from the open side at the top of the installation groove 2121, and the second mounting block 213 can be limited by the plurality of convex columns, making the installation of the second mounting block 213 more convenient.

[0094] Among them, the valve body structure 22 and the glue storage cylinder 23 can be communicated through a base 221. Specifically, in combination with Figures 12 to 14 shown in the figure, a glue guiding channel 2211 is formed on the base 221, and one end of the glue guiding channel 2211 forms a glue outlet 2212; the glue storage cylinder 23 is arranged on the base 221, and the storage cavity cylinder is communicated with the glue guiding channel 2211; the valve body structure 22 is arranged on the base 221 and is used to adjust the glue output at the glue outlet 2212. The dispensing assembly 2 further includes a cooling structure 24, and the cooling structure 24 is arranged on one side of the valve body structure 22 and is used to cool the valve body structure 22.

[0095] Further, for the glue storage cylinder 23, the glue storage cylinder 23 is used to store glue. The glue storage cylinder 23 is connected to the glue guiding channel 2211 on the base 221, and the glue can flow into the glue guiding channel 2211 and flow out from the glue outlet 2212. By providing a valve body structure 22, the valve body structure 22 can control the glue output volume at the glue outlet 2212 to ensure that the glue output volume is within a suitable dispensing range. Moreover, the valve body structure 22 can be cooled by a cooling mechanism. After the valve body structure 22 works for a long time, the cooling mechanism can effectively reduce the temperature on the valve body structure 22 to ensure that the temperature at the valve body structure 22 always remains within a suitable temperature range, so as to ensure the adjustment accuracy of the valve body structure 22, enable the glue dispenser 100 to maintain a stable glue output volume, and continuously ensure a better dispensing effect.

[0096] When the glue dispenser 100 is working normally, the glue storage cylinder 23 is arranged on the base 221, and the mouth of the glue storage cylinder 23 is inserted into the glue guiding channel 2211. The mouth of the glue storage cylinder 23 is located at the bottom of the glue storage cylinder 23 so that the glue can better flow into the glue guiding channel 2211 under the action of gravity. The valve body structure 22 is arranged on the base 221, and the glue outlet 2212 is located at the bottom of the base 221.

[0097] Preferably, in combination with Figure 12 and Figure 13As shown, the valve body structure 22 includes a housing 222, a top rubber rod 223, a crimping member, and an adjusting member 225. The housing 222 is disposed on the base 221. The top rubber rod 223 is movably disposed on the housing 222. At least a part of the top rubber rod 223 can extend out of the housing 222 to extend into the glue outlet 2212. The top rubber rod 223 has a moving stroke along the axial direction of the glue outlet 2212. Preferably, the top rubber rod 223 extends in the up and down direction. The bottom of the top rubber rod 223 extends into the glue outlet 2212, and the top of the top rubber rod 223 is disposed inside the housing 222. The crimping member is rotatably disposed inside the housing 222 and crimps on the top rubber rod 223. The adjusting member 225 is movably disposed inside the housing 222 and is in contact connection with the crimping member. The adjusting member 225 moves under the action of an external force to drive the crimping member to rotate, so that the crimping member can press on the top rubber rod 223 to adjust the depth of the top rubber rod 223 extending into the glue outlet 2212. During operation, by adjusting the adjusting member 225 to drive the crimping member to move, the top rubber rod 223 moves to adjust the depth of the top rubber rod 223 extending into the glue outlet 2212. That is, when the distance between the top rubber rod 223 and the glue outlet end of the glue outlet 2212 is farther, the amount of glue in the glue outlet 2212 is more. Therefore, when the glue is ejected from the glue outlet 2212 through the top rubber rod 223, the amount of ejected glue is also more. On the contrary, when the distance between the top rubber rod 223 and the glue outlet end of the glue outlet 2212 is closer, the amount of glue in the glue outlet 2212 is less. Therefore, when the glue is ejected from the glue outlet 2212 through the top rubber rod 223, the amount of ejected glue is also less, thereby controlling the glue output of the dispenser 100.

[0098] Further, as Figure 13 shown in, the crimping member includes a crimping rod 224. One end of the crimping rod 224 crimps on the top rubber rod 223. Preferably, the crimping rod 224 crimps on the top end of the top rubber rod 223. The adjusting member 225 crimps on the other end of the crimping rod 224. The middle of the crimping rod 224 is rotatably connected to the housing 222. When the adjusting member 225 presses the crimping rod 224 under the action of an external force, the crimping rod 224 rotates to move the top rubber rod 223 in the direction of withdrawing from the glue outlet 2212. The crimping rod 224 forms a crimping lever. By pressing one end of the crimping rod 224 by the adjusting member 225, the other end of the crimping rod 224 can move in the reverse direction.

[0099] It can be understood that the movement of the adjusting member 225 can be manually moved by a person, or the adjusting member 225 can be driven by a driving device.

[0100] In one embodiment, the adjusting member 225 is provided as a telescopic rod. The adjusting member 225 extends to press the crimping rod 224, causing the top glue rod 223 to move in the direction of withdrawing from the glue outlet 2212; the adjusting member 225 contracts to move in the direction away from the crimping rod 224, causing the top glue rod 223 to move in the direction of extending into the glue outlet 2212. The telescopic movement of the telescopic rod can be driven by a driver so that the telescopic rod can press on the crimping rod 224, thereby adjusting the position of the top glue rod 223 to adjust the glue output or resist the outflow of glue.

[0101] Preferably, the adjusting member 225 is provided as a piezoelectric ceramic member. According to the properties of piezoelectric ceramic materials, piezoelectric ceramics have the property of spontaneous polarization, and the spontaneous polarization can be changed under the action of an external electric field. When an external electric field identical to the spontaneous polarization is applied, it is equivalent to enhancing the polarization intensity, and the increase in polarization intensity causes the piezoelectric ceramic member to elongate along the polarization direction. On the contrary, if a reverse electric field is applied, the piezoelectric ceramic member shortens along the polarization direction. Among them, the adjusting member 225 can be electrically connected to a power supply device. When an electric field is connected to the adjusting member 225, the adjusting member 225 is deformed by adjusting the direction of the electric field to achieve telescopic movement in the up and down directions, and then can press on the crimping rod 224. This makes the structure of the adjusting member 225 simpler, and thus the internal structure of the valve body structure 22 is simpler, which is beneficial to the heat dissipation of the valve body structure 22.

[0102] Moreover, the end face of the adjusting member 225 in contact with the crimping rod 224 is provided in an arc shape that is adapted to each other, so that it is not easy to slip when the adjusting member 225 presses the crimping rod 224, and the contact is more stable. Therefore, the pressing of the adjusting member 225 on the crimping rod 224 is more stable, making the glue output more accurate.

[0103] As Figure 14 shown, a limit pin 227 is further provided in the housing 222. When the adjusting member 225 presses the crimping rod 224 to a preset position, the crimping rod 224 abuts against the limit pin 227. That is, when the adjusting member 225 presses the crimping rod 224 downward and the adjusting member 225 is at the lowest position, the crimping rod 224 can abut against the limit pin 227. The downward pressing amount of the adjusting member 225 can be controlled by the limit pin 227, and then the highest position of the top glue rod 223 can be controlled to control the maximum glue output. Of course, the specific maximum glue output can be set according to the size and requirements of the actual equipment, and no specific limitation is made here.

[0104] In addition, in combination with Figure 13 and Figure 14As shown, the valve body structure 22 also includes an elastic telescopic member 226, which is sleeved on the outer side of the top glue rod 223 and respectively abuts between the shell 222 and the top glue rod 223. The elastic telescopic member 226 can be set as a telescopic spring. For example, when the adjusting member 225 is not crimped to the crimping rod 224, the top glue rod 223 is in an initial position, and when the adjusting member 225 is crimped to the crimping rod 224, the elastic telescopic member 226 is in an extended state. When the adjusting member 225 moves upward, the pressure on the crimping rod 224 is gradually reduced, and the crimping rod 224 can rotate under the elastic restoring force of the elastic telescopic member 226, so that the top glue rod 223 can be restored to the initial position. The reset of the top glue rod 223 does not require additional driving force, and the operation is simpler and the structure is simpler.

[0105] When the adjusting member 225 is a piezoelectric ceramic member, since the piezoelectric ceramic will generate more heat after being energized, in order to dissipate heat better and faster. Preferably, the cooling structure 24 includes a heat dissipation structure and a fan 244, wherein the heat dissipation structure is arranged outside the housing 222 and corresponds to the adjusting member 225, and the fan 244 is arranged on the side of the heat dissipation structure facing away from the housing 222. The heat inside the valve body structure 22 can be exported through the heat dissipation structure, and the exported heat can be quickly dissipated through the fan 244 to achieve effective and rapid heat dissipation and ensure the cooling of the valve body structure 22.

[0106] Furthermore, combined with Figure 13 and Figure 15 As shown, the heat dissipation structure includes a cooling block 241, a cooling fin 242 and a semiconductor heat dissipation block 243. The cooling block 241 is arranged in contact with the housing 222, the semiconductor heat dissipation block 243 is arranged in contact with the cooling block 241, the cooling fin 242 is arranged in the clamping groove formed between the cooling block 241 and the semiconductor heat dissipation block 243, and the fan 244 is located on the outside of the heat dissipation block. The cold side of the semiconductor heat dissipation block 243 is in contact with the cooling fin 242 and the cooling block 241, and the heat in the valve body structure 22 can be quickly extracted. The heat dissipation end of the semiconductor heat dissipation block 243 is opposite to the fan 244, and then the heat on the semiconductor heat dissipation block 243 can be quickly blown away by the fan 244, and the heat dissipation efficiency is high, so as to ensure that the valve body structure 22 is always kept within a suitable working range, thereby ensuring the working stability and accuracy of the valve body structure 22, so that the glue dispensing machine 100 maintains a stable glue output.

[0107] Preferably, combined Figure 2 and Figure 3As shown, the dispensing assembly 2 has a moving stroke in the vertical direction of the frame 1 and in the lateral direction of the frame 1. The dispenser 100 further includes a dispensing drive assembly. The dispensing drive assembly includes a lateral moving frame provided on the support base plate 11, a lateral moving frame movably provided in the lateral direction on the lateral moving frame, a lifting block movably provided in the vertical direction of the frame 1 on the lateral moving frame, a lateral drive connected to the lateral moving frame, and a lifting drive connected to the lifting block. The support plate 211 is connected to the lifting block. The lateral drive drives the lateral moving frame to move in the lateral direction of the frame 1, driving the lifting block and the support plate 211 to move together in the lateral direction of the frame 1, so that the dispensing assembly 2 can move in the lateral direction of the frame 1, and thus the glue outlet 2212 can move in the lateral direction of the frame 1; by driving the lifting block to move in the vertical direction of the frame 1 through the lifting drive, driving the support plate 211 to move together in the vertical direction of the frame 1, so that the dispensing assembly 2 can move in the vertical direction of the frame 1, thereby adjusting the height of the glue outlet 2212 to adjust the distance between the glue outlet 2212 and the product to be dispensed.

[0108] Moreover, in combination with Figure 2 、 Figure 4 and Figure 5 as shown, the dispenser 100 further includes a camera detection assembly 9. The camera detection assembly 9 is provided on the side of the lateral moving frame facing away from the dispensing assembly 2. The camera detection assembly 9 can be used to obtain image information of the product after dispensing. The camera detection assembly 9 is electrically connected to the control device. The control device can obtain the image information of the camera detection assembly 9, compare the image information with the preset image information stored in the control device, so as to judge whether there is a problem with dispensing. The dispensing image information can be obtained immediately after dispensing, and the detection is faster, and the dispensing quality problem can be found more timely.

[0109] The camera detection component 9 can move horizontally along the frame 1 together with the horizontal moving frame. The camera detection component 9 includes a camera support 91, a detection camera 92 provided on the camera support 91, a reflective structure, and a light source 93. The camera support 91 is generally in an "L" shape, having a first support arm extending horizontally along the frame 1 and a second support arm extending vertically along the frame 1. The light source 93 is provided at the bottom of the second support arm, which can be closer to the product during shooting, resulting in a better light filling effect. The detection camera 92 is arranged horizontally along the frame 1, and through the reflective structure, the product image below the light source 93 can be reflected to the detection camera 92. The camera detection component 9 and the dispensing component 2 are arranged horizontally along the frame 1, so that less space in the longitudinal direction of the frame 1 is occupied, thereby making the entire dispensing machine 100 smaller in the longitudinal dimension, more compact in structure, and occupying less space.

[0110] For the weighing component 3, the weighing component 3 is mainly used to weigh the single-time dispensing weight of the dispensing component 2, so that the dispensing amount for different products can be controlled more precisely. Specifically, as Figure 7 shown, the weighing component 3 includes a mounting base 31, a weighing detector 32, and a measuring container 33. The mounting base 31 is provided on the frame 1; the weighing detector 32 is provided on the mounting base 31; the measuring container 33 is provided on the weighing detector 32 and includes a cup body and a cup cover. The cup body is provided on the weighing detector 32, and the cup cover is covered on the cup body and is provided with a first through hole 34. When the dispensing component 2 starts dispensing for the first time or after a certain period of time, the dispensing component 2 can be moved through the dispensing drive component, so that the glue outlet 2212 of the dispensing component 2 moves to be opposite to the first through hole 34, and then glue is dispensed, so that the glue falls into the cup body. Thus, the weight of the glue can be obtained through the weighing detector 32 below the cup body, and the single-time dispensing weight of the dispensing component 2 can be obtained, so as to observe the change of the dispensing amount of the dispensing component 2 in real time and ensure the continuous and stable operation of the dispensing machine 100.

[0111] For the position detection component 4, in combination with Figure 2 and Figure 6As shown, the position detection component 4 includes a height measurement base plate 41, a height measurement cover 42, an adjustment plate 43, and a height detector 44. The height measurement base plate 41 is arranged on the frame 1; the height measurement cover 42 is arranged on the height measurement base plate 41; the adjustment plate 43 is arranged inside the height measurement cover 42 and can move along the up and down direction of the frame 1; the height detector 44 is arranged on the adjustment plate 43, and its top can be exposed from the top of the height measurement cover 42. The initial position of the glue outlet 2212 of the dispensing component 2 can be calibrated through the height detector 44. Specifically, when the dispensing component 2 performs the first dispensing, the glue outlet 2212 of the dispensing component 2 can be moved to the position of the height detector 44, and the height of the glue outlet 2212 is calibrated through the height detector 44. The height detector 44 is electrically connected to the control device, and the dispensing height of the glue outlet 2212 can be obtained through the control device, thereby ensuring the accuracy of the dispensing height. Moreover, since the adjustment plate 43 can move along the up and down direction of the frame 1, for different types of products, the dispensing height is also different. Therefore, by adjusting the position of the adjustment plate 43 in the up and down direction, the height of the height detector 44 can be adjusted, so as to be applicable to the height calibration requirements of various products.

[0112] Moreover, as shown in Figure 2 and Figure 5 , the position detection component 4 further includes a laser detector 45. The laser detector 45 is connected to the support plate 211 and is arranged corresponding to the glue outlet 2212, and is used to detect the height of the glue outlet 2212; the control device is electrically connected to both the laser detector 45 and the height detector 44, and is used to obtain the measurement values of the laser detector 45 and the height detector 44 and compare them. The laser detector 45 includes a laser mounting plate and a laser position sensor arranged on the laser mounting plate. The laser mounting plate is connected to the support plate 211 and can move relative to the support plate 211 along the up and down direction, so as to adjust the height of the laser position sensor for different types of the dispensing components 2 to make the detection more accurate. The height position of the glue outlet 2212 can be calibrated through the height detector 44, and the height difference between the glue outlet 2212 and the product can be obtained in real time through the laser detector 45, which better ensures the accuracy of the dispensing height.

[0113] Since during the dispensing process of the dispensing component 2, glue residue or wire drawing may occur at the glue outlet 2212, which affects the subsequent dispensing effect. Therefore, as shown in Figure 2 and Figure 8As shown, the dispenser 100 further includes a glue removing assembly 5. The glue removing assembly 5 is used to remove the residual glue at the glue outlet 2212 of the dispensing assembly 2. The glue removing assembly 5 includes a glue removing chamber 51, a glue removing cover 52 and a glue sucking nozzle 53. The glue removing chamber 51 is arranged on the frame 1, is hollow and has an open top. The glue removing chamber 51 is adapted to be connected to a suction device. The glue removing cover 52 is covered on the opening of the glue removing chamber 51 and is provided with a second through hole. The glue sucking nozzle 53 is arranged at the second through hole and blocks the second through hole. At least part of the glue sucking nozzle 53 can be exposed from the second through hole. After the dispensing assembly 2 works for a preset time, the dispensing drive assembly drives the dispensing assembly 2 to move to the glue removing assembly 5 so that the glue outlet 2212 is aligned with the second through hole. Under the action of the negative pressure in the glue removing chamber 51, the residual glue at the glue outlet 2212 can be sucked into the glue removing chamber 51 through the glue sucking nozzle 53 to clean the glue outlet 2212, so that a good dispensing effect can always be ensured at the glue outlet 2212.

[0114] Moreover, the dispenser 100 further includes a conveying assembly 6. The conveying assembly 6 is used to convey the products to be dispensed, so that the products can be automatically transferred to the dispensing station and can be transferred out of the dispenser 100 after dispensing is completed. Specifically, in combination with Figure 2 and Figure 3 As shown, the conveying assembly 6 includes a conveyor belt 61 extending longitudinally along the frame 1. The conveyor belt 61 can be a flat conveyor belt 61, a round belt or a chain, and the width of its conveying track can be adjusted to meet the conveying requirements of products with different widths. The position detection assembly 4, the weighing assembly 3 and the glue removing assembly 5 are arranged in sequence on the same side of the conveyor belt 61, and the first through hole 34 and the second through hole are in the same straight line longitudinally, which is convenient for controlling the position of the glue outlet 2212.

[0115] In addition, as shown in Figure 3 , a glue scraping assembly 7 is further arranged on the other side of the conveyor belt 61. The glue scraping assembly 7 includes a glue scraping mounting plate, glue scraping bristles 71 and a glue scraping cup 72. When the amount of residual glue is large, the glue outlet 2212 can be moved to the glue scraping bristles 71, and the residual glue can be scraped off by the glue scraping bristles 71 to ensure that the glue outlet 2212 is cleaner and the dispensing effect is better.

[0116] In one embodiment, in combination with Figure 3 and Figure 16As shown, the dispensing machine 100 further includes a lifting mechanism 8. The lifting mechanism 8 includes a lifting base 81, a lifting plate 82, a lifting drive structure 83, and a gas supply structure 84. The lifting plate 82 is movably disposed on the lifting base 81 and has at least a moving stroke in the vertical direction of the lifting base 81. The lifting drive structure 83 is disposed on the lifting base 81 and is connected to the lifting plate 82. The lifting drive structure 83 drives the lifting plate 82 to move in the vertical direction of the lifting base 81. Among them, the lifting plate 82 includes a first plate member 821 and a second plate member 822 that are spaced apart in the vertical direction of the lifting base 81, and a buffer member 823 disposed between the first plate member 821 and the second plate member 822. The lifting drive structure 83 is connected to the first plate member 821. An interval space is formed between the first plate member 821 and the second plate member 822. The gas supply structure 84 includes a suction nozzle 841 disposed on the second plate member 822. One end of the suction nozzle 841 protrudes from the top of the second plate member 822, and the other end of the suction nozzle 841 is received in the interval space.

[0117] In this embodiment, the lifting drive structure 83 drives the lifting plate 82 to move up and down along the lifting base 81 to realize the lifting support of the product and the separation from the product, so that the product can be better fixed during dispensing and can be moved and transported after dispensing. Moreover, the lifting plate 82 includes a first plate member 821 and a second plate member 822. The second plate member 822 contacts the product. The lifting drive structure 83 drives the first plate member 821 to move, driving the second plate member 822 to move together. And a buffer member 823 is disposed between the first plate member 821 and the second plate member 822. When the lifting stroke of the lifting drive mechanism is certain, after the second plate member 822 contacts the product, the product can press down the second plate member 822, so that there is no hard contact between the second plate and the product, and the second plate member 822 has a certain buffer movement space, so that the product can be better protected and the product is not easily damaged. Moreover, a gas supply structure 84 is also provided, so that an adsorption force can be formed on the second plate member 822, and the product is adsorbed and fixed through the suction nozzle 841 on the second plate member 822, further preventing the product from moving and making the product fixation more stable and reliable.

[0118] Wherein, the first plate member 821 and the second plate member 822 are both arranged in a substantially square flat plate shape, and the area of the second plate member 822 is larger than that of the first plate member 821. It should be noted that when the lifting mechanism 8 is working properly, the second plate member 822 is located above the first plate member 821. In the direction from top to bottom, the orthographic projection of the second plate member 822 on the first plate member 821 can completely cover the first plate member 821. The first plate member 821 and the second plate member 822 are arranged in parallel, so that when the lifting drive structure 83 drives the first plate member 821 to move in the up and down direction, the second plate member 822 can be driven to move in the up and down direction together.

[0119] Further, as shown in combination with Figure 16 and Figure 17 the lifting mechanism 8 further includes a plurality of first guiding structures 85, and the plurality of first guiding structures 85 are connected between the first plate member 821 and the second plate member 822; a plurality of buffer members 823 are provided, and the plurality of buffer members 823 are arranged in one-to-one correspondence with the plurality of first guiding structures 85. Preferably, four first guiding structures 85 are provided, and the four first guiding structures 85 are respectively arranged corresponding to the four corners of the first plate member 821 and the second plate member 822. Under the guiding action of the first guiding structures 85, the second plate member 822 moves more stably relative to the first plate member 821, so the support for the product is more stable.

[0120] Preferably, as shown in combination with Figure 17 and Figure 18 each of the first guiding structures 85 includes a first guiding cylinder 851 provided on the first plate member 821 and a first guiding shaft 852 with one end connected to the second plate member 822, and the other end of the first guiding shaft 852 is movably sleeved in the first guiding cylinder 851; each of the buffer members 823 includes a telescopic spring, and the telescopic spring is sleeved outside the first guiding shaft 852 and abuts against the second plate member 822 and the first guiding cylinder 851 at both ends respectively. The first guiding cylinder 851 is arranged in a substantially cylindrical shape with both ends open, the middle part of the guiding cylinder is fixedly sleeved on the first plate member 821, and the first guiding shaft 852 is slidably sleeved inside the first guiding cylinder 851 in the up and down direction. By the two ends of the telescopic spring in its telescopic direction respectively abutting against the second plate member 822 and the first guiding cylinder 851. After the lifting drive structure 83 drives the first plate member 821 to rise by a preset height, the second plate member 822 abuts against the bottom of the product. Since the product is clamped and fixed on the conveying structure, therefore, the second plate member 822 can be pressed down by the product, and under the action of the telescopic spring, the second plate member 822 can be in a proper position and always support the bottom of the product.

[0121] Among them, as Figure 17 and Figure 18 shown, the second plate member 822 includes a jacking bottom wall 8221, a jacking side wall 8222 protruding from the outer peripheral side of the jacking bottom wall 8221, and ribs 8223 protruding from the jacking bottom wall 8221. The jacking side wall 8222 is arranged in a ring shape, and the ribs 8223 are also arranged in a ring shape and surround the inner ring side of the jacking side wall 8222. Through the jacking side wall 8222, when the second plate member 822 supports the bottom of the product, a certain interval is formed between the bottom of the product and the jacking bottom wall 8221, so that it is convenient for the suction nozzle 841 to form a vacuum in the interval to adsorb and fix the product.

[0122] Specifically, a plurality of mounting holes are provided on the jacking bottom wall 8221, and a plurality of suction nozzles 841 are provided. The plurality of suction nozzles 841 are respectively mounted in the plurality of mounting holes, and the suction ports of the plurality of suction nozzles 841 are flush with the upper surface of the jacking bottom wall 8221. Among them, the air supply structure 84 may further include a suction device and a connecting pipe fitting connecting the suction device and the plurality of suction nozzles 841. The suction device can be set as a blower or a vacuum pump. By the operation of the suction device, a vacuum is formed at the plurality of suction nozzles 841, and then the product is adsorbed and fixed on the second plate member 822, ensuring stable and reliable support and fixation of the product.
