[0050] The present utility model provides a multi-head dispensing device, which is applicable to the application scenario of dispensing on a workpiece to be dispensed, and can improve the structural compactness of the device while improving production efficiency.

[0051] See Figure 1 , the multi-head dispensing device provided in this embodiment includes a conveying device 100, at least two dispensing heads 200 arranged along the conveying device 100, and an auxiliary mechanism 300 that is correspondingly arranged for each of the dispensing heads 200 and is used to cooperate with the corresponding dispensing head 200 for glue discharging, pre-dispensing, and glue wiping.

[0052] See Figure 2 and Figure 3 , the conveying device 100 includes two belts 1 arranged at intervals, at least two lifting mechanisms 2 correspondingly arranged for each of the dispensing heads 200, and at least two clamping mechanisms 3 correspondingly arranged for each of the dispensing heads 200. Each of the lifting mechanisms 2 is located between the two belts 1; the clamping mechanism 3 includes two clamping components 301 that are higher than the belt 1 and are oppositely arranged, wherein the clamping component 301 is provided with an avoidance space, and the auxiliary mechanism 300 is installed in the avoidance space.

[0053] Optionally, the dispensing head 200 includes a dispensing nozzle 4 and an XYZ three-way drive mechanism 5 for driving the movement of the dispensing nozzle 4.

[0054] The multi-head dispensing device provided in this embodiment works as follows:

[0055] ① The conveyor belt 1 conveys the first carrier loaded with the workpiece to be dispensed above the first lifting mechanism 2. The first lifting mechanism 2 jacks up the first carrier. After the first clamping mechanism 3 clamps the first carrier, the first dispensing head 200 can sequentially dispense the workpiece to be dispensed in the first carrier.

[0056] ② The first lifting mechanism 2 retracts downward. The conveyor belt 1 conveys the second carrier loaded with the workpiece to be dispensed above the second lifting mechanism 2. The second lifting mechanism 2 jacks up the second carrier. After the second clamping mechanism 3 clamps the second carrier, the second dispensing head 200 can sequentially dispense the workpiece to be dispensed in the second carrier.

[0057] And so on, the conveyor belt 1 can sequentially convey each carrier to each clamping mechanism 3 so that multiple dispensing heads 200 can perform dispensing operations synchronously, thereby improving production efficiency.

[0058] Furthermore, an avoidance space is provided at the clamping assembly 301, and the auxiliary mechanism 300 is installed in the avoidance space, thereby avoiding the auxiliary structure occupying more extra space to achieve the effect of a compact structure.

[0059] Therefore, the multi-head dispensing device provided in this embodiment can improve the structural compactness of the device while improving production efficiency.

[0060] The clamping assembly 301 includes a transverse clamping plate 3011 and a clamping plate linear drive mechanism 3012. Among them, the transverse clamping plate 3011 is provided with the avoidance space; the drive end of the clamping plate linear drive mechanism 3012 is connected to the transverse clamping plate 3011 and is used to drive the transverse clamping plate 3011 to approach or move away from the carrier loaded with the workpiece to be dispensed.

[0061] In this embodiment, the auxiliary mechanism 300 includes a glue discharge cup 6 for storing glue residues, a pre-dispensing mechanism 7 for pre-dispensing the dispensing head 200, and a glue wiping mechanism 8 for wiping the dispensing head 200.

[0062] Accordingly, the avoidance space includes a glue cup slot 3011a located at the middle position of the transverse clamping plate 3011 for fixing the glue discharging cup 6, and an avoidance groove 3011b located at the edge position of the transverse clamping plate 3011 for accommodating the pre-dispensing mechanism 7 and the glue wiping mechanism 8; wherein, the opening of the avoidance groove 3011b on the clamping mechanism 3 faces away from the other clamping assembly 301.

[0063] The opening of the avoidance groove 3011b can prevent the transverse clamping plate 3011 from colliding with the pre-dispensing mechanism 7 and the glue wiping mechanism 8 when moving, thereby avoiding the situation of movement interference. Further, setting the opening of the avoidance groove 3011b to face away from the other clamping assembly 301 can maintain the integrity of the clamping surface of the transverse clamping plate 3011 for clamping the carrier, thereby ensuring a good clamping effect.

[0064] Optionally, the pre-dispensing mechanism 7 includes a pressure sensor 701 and a dispensing weighing platform 702. The glue wiping mechanism 8 includes two oppositely arranged wiping plates 801, a jaw cylinder 802 for driving the two wiping plates 801 to approach or separate from each other, a cleaning paper 803 wound around the two wiping plates 801, and a rotating roller set for driving the cleaning paper 803 to rotate.

[0065] The wiping plate 801 is provided with a guiding groove 8011 for accommodating the cleaning paper 803, and silica gel pads 804 are provided on the surfaces of the two wiping plates 801 that are close to each other.

[0066] Before dispensing the workpiece to be dispensed, the XYZ three-way driving mechanism 5 first moves the dispensing nozzle 4 above the glue discharging cup 6 and discharges the residual glue slag on the dispensing nozzle 4 into the glue discharging cup 6; then, the XYZ three-way driving mechanism 5 drives the dispensing nozzle 4 to move onto the pressure sensor 701. When the dispensing nozzle 4 presses down on the pressure sensor 701, the pressure sensor 701 will detect the pressure value, and based on this, the dispensing nozzle 4 can be positioned; then, the XYZ three-way driving mechanism 5 moves the dispensing nozzle 4 to the dispensing weighing platform 702 for dispensing. If the weight value obtained by the dispensing weighing platform 702 is within the preset range, it means that the dispensing amount is appropriate; the XYZ three-way driving mechanism 5 first moves the dispensing nozzle 4 between the two wiping plates 801, and the jaw cylinder 802 drives the two wiping plates 801 to approach each other, so that the cleaning paper 803 can wipe the residual glue on the dispensing nozzle 4; finally, the XYZ three-way driving mechanism 5 can drive the dispensing nozzle 4 to perform a dispensing operation on the workpiece to be dispensed in the carrier.

[0067] Optionally, the number of the dispensing heads 200 is two, three, four or more, and this embodiment does not limit this.

[0068] In summary, the multi-head dispensing device provided by this embodiment has the following advantages:

[0069] ① The conveyor belt 1 sequentially transports each carrier to each clamping mechanism 3, so that multiple dispensing heads 200 can perform dispensing operations synchronously, thereby improving production efficiency;

[0070] ② An avoidance space is provided at the clamping assembly 301, and the auxiliary mechanism 300 is installed in the avoidance space, so that the auxiliary structure can be prevented from occupying more extra space, so as to achieve the effect of a compact structure;

[0071] ③ The auxiliary mechanism 300 can cooperate with the dispensing head 200 to perform glue discharging, pre-dispensing and glue wiping operations, so as to improve the dispensing effect and ensure the dispensing quality.

[0072] It should be noted that the linear drive mechanism mentioned in the present invention can be a cylinder, a hydraulic cylinder, an electric cylinder or a motor screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, a brushless motor or a rotary cylinder, etc. The specific structural forms of the linear drive mechanism and the rotary drive mechanism in the present invention are not limited.

[0073] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification using the content recorded in the text and drawings of the specification of this application based on the essential concept of this application, as well as the technical solutions of the above embodiments directly or indirectly implemented in other related technical fields, are all included in the patent protection scope of this application.
