Description

Technical Field

[0001] This invention relates to the field of ultrasonic welding technology, and more particularly to an ultrasonic welding machine. Background Technology

[0002] Cryopreservation tubes are used for the preservation of biological samples and consist of a carrier rod, an outer tube, a marker key, and an inner tube. Before loading the biological sample onto the carrier rod, the carrier rod is first secured to the front end of the holder pen to form an assembly, thereby extending the overall length to facilitate subsequent freezing operations. After loading the biological sample, the carrier rod and the inner tube need to be welded together. However, since the carrier rod is sleeved on the front end of the holder pen, during the welding process, the inner tube is usually placed in an ultrasonic welding head, and then the assembly consisting of the carrier rod and the holder pen is inserted into the inner tube for welding. During this process, relative displacement may occur between the carrier rod, the holder pen, and the inner tube, resulting in the carrier rod and the inner tube not being welded to the correct position. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an ultrasonic welding machine that can avoid the situation where the carrier rod and the inner sleeve cannot be welded to the appropriate position during welding.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] An ultrasonic welding machine includes a clamp and an ultrasonic welding head. The ultrasonic welding head is disposed on one side of the clamp. The clamp includes a base, a clamping block, and a clamping block driving mechanism. The base has a slot adapted to fit an assembly. The clamping block is adapted to move toward the slot under the drive of the clamping block driving mechanism so as to cooperate with the slot to clamp the assembly.

[0006] It also includes a drive mechanism, wherein the clamp or the ultrasonic welding head is mounted on the drive end of the drive mechanism, and is adapted to be driven by the drive mechanism to cause the clamp and the ultrasonic welding head to move toward each other, so that the part of the clamped assembly to be welded can enter the ultrasonic welding head for welding.

[0007] Furthermore, a card block is provided on the side of the card holder facing the card slot, and a positioning groove adapted to the card block is provided on the base.

[0008] Furthermore, the card block has a slot adapted to the surface of the cryopreservation tube.

[0009] Furthermore, it also includes a first position sensor and a second position sensor, wherein the first position sensor is adapted to detect whether the clamping block is in a preset position, and the second position sensor is adapted to detect whether the inner sleeve is placed in a preset processing position.

[0010] Furthermore, the clamping block driving mechanism includes a clamping block driving motor, and the clamping block is mounted on the main shaft of the clamping block driving motor to be adapted to swing toward the clamping slot under the drive of the clamping block driving motor.

[0011] Furthermore, the clamping block driving mechanism includes a clamping block driving electric cylinder, which is located above the card slot. The clamping block is mounted on the driving end of the clamping block driving electric cylinder to be adapted to move toward the card slot under the drive of the clamping block driving electric cylinder.

[0012] Furthermore, the driving mechanism includes a stage and a stage driving mechanism mounted on the lower end of the stage. The base and the clamping block driving mechanism are both mounted on the stage and are adapted to move toward or away from the ultrasonic welding head under the drive of the stage driving mechanism.

[0013] Furthermore, the driving mechanism also includes a guide rail, and a slider that slides with the guide rail is provided at the lower end of the platform.

[0014] Furthermore, it also includes a limiting damping element, which is adapted to abut against the slider when the cryopreservation tube held by the fixture reaches a preset processing position, so as to prevent the stage drive mechanism from being stopped.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention utilizes a clamping block and a clamping block drive mechanism to firmly hold the part of the assembly to be welded, namely the carrier rod. A slot further limits the positioning of the tube-holding pen part within the assembly, preventing relative displacement between the carrier rod and the tube-holding pen during welding. The drive mechanism automatically transports the frozen tube held by the clamp to the ultrasonic welding head for welding, thus achieving semi-automation of the welding process and reducing the operator's workload.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0026] like Figure 1-6 As shown, the present invention discloses an ultrasonic welding machine, including a clamp 10 and an ultrasonic welding head 30. The ultrasonic welding head 30 is disposed on one side of the clamp 10. The clamp 10 includes a base 101, a clamping block 102 and a clamping block 102 driving mechanism 20. The base 101 has a slot 1011 adapted to the assembly. The clamping block 102 is adapted to move toward the slot 1011 under the drive of the clamping block 102 driving mechanism 20 so as to cooperate with the slot 1011 to clamp the load assembly.

[0027] It also includes a drive mechanism 20, wherein the clamp 10 or the ultrasonic welding head 30 is mounted on the drive end of the drive mechanism 20, so as to be adapted to move the clamp 10 and the ultrasonic welding head 30 toward each other when driven by the drive mechanism 20, so that the part of the clamped assembly to be welded can enter the ultrasonic welding head 30 for welding.

[0028] During operation, the user first places the cryogenic tube to be welded into the slot 1011, and then activates the clamping block 102 drive mechanism 20. The clamping block 102 drive mechanism 20 drives the clamping block 102 to move toward the slot 1011, so that the clamping block 102 abuts against the carrier rod part in the assembly in the slot 1011, thereby clamping the carrier rod. At the same time, the slot 1011 can limit the tube holding pen part in the assembly to prevent relative displacement between the carrier rod and the tube holding pen. The drive mechanism 20 is activated to drive the clamp 10, the carrier rod clamped by the clamp 10 and the ultrasonic welding head to move toward each other, so that the part of the carrier rod to be welded can enter the ultrasonic welding head 30 for welding.

[0029] The present invention uses a clamping block 102 and a clamping block 102 driving mechanism 20 to firmly clamp the welding part of the assembly, namely the carrier rod part. In addition, the slot 1011 limits the position of the tube holding pen part in the assembly, thereby preventing relative displacement between the carrier rod and the tube holding pen during the welding process. Furthermore, the driving mechanism 20 can automatically transport the cryopreservation tube held by the clamp 10 to the ultrasonic welding head 30 for welding, thereby realizing semi-automation of the welding process and reducing the workload of the operator.

[0030] Preferably, in order to prevent the clamping block 102 from moving relative to the base 101 during the clamping process, which would cause the carrier rod to loosen, in this embodiment, a clamping block 1021 is also provided on the side of the clamping block 102 facing the clamping groove 1011, and a positioning groove 1012 adapted to the clamping block 1021 is provided on the base 101.

[0031] When clamped, the clamping block 1021 can be embedded in the positioning groove 1012, thereby preventing the clamping block 102 from moving relative to the base 101, thus ensuring the stability of the clamping block 102 when clamped to the base 101.

[0032] Preferably, in this embodiment, the locking block 1021 is provided with a locking slot that is adapted to the surface of the carrier rod, so that the locking block 1021 can fit more closely to the carrier rod, thereby improving the stability of clamping.

[0033] Preferably, this embodiment also includes a first position sensor 40 and a second position sensor 50. The first position sensor 40 is adapted to detect whether the holding block 102 is in a preset position, and the second position sensor 50 is adapted to detect whether the inner sleeve is placed in a preset processing position.

[0034] In this embodiment, the preset position is the position of the clamping block 102 when it is not clamped, and the preset processing position is the position of the assembly clamped by the fixture 10 when it is inserted into the ultrasonic welding head 30.

[0035] During operation, when the first position sensor 40 detects that the clamping block 102 is in a preset position, it transmits the position signal of the clamping block 102 to the control terminal of the ultrasonic welding machine. The control terminal controls the clamping block 102 drive mechanism 20 to start, so as to clamp the assembly to be welded, and controls the drive mechanism 20 to work, so as to drive the clamp 10 to move towards the ultrasonic connector, so that the part to be welded, i.e. the carrier rod part, of the clamped assembly can be inserted into the ultrasonic welding head 30. At this time, the second position sensor 50 will detect the position of the cryopreservation tube and transmit the information to the control terminal, which controls the ultrasonic welding head 30 to start, so as to weld the cryopreservation tube.

[0036] Preferably, in this embodiment, the clamping block 102 driving mechanism 20 includes a clamping block driving motor 103, and the clamping block 102 is mounted on the main shaft of the clamping block driving motor 103 to be adapted to swing toward the clamping slot 1011 under the drive of the clamping block driving motor 103.

[0037] Preferably, the clamping block 102 driving mechanism 20 includes a clamping block 102 driving electric cylinder, which is located above the clamping slot 1011. The clamping block 102 is mounted on the driving end of the clamping block 102 driving electric cylinder to be adapted to move toward the clamping slot 1011 under the drive of the clamping block 102 driving electric cylinder.

[0038] The drive mechanism 20 includes a stage 201 and a stage drive mechanism 202 mounted on the lower end of the stage 201. The base 101 and the holding block 102 are both mounted on the stage 201 and are adapted to move toward or away from the ultrasonic welding head 30 under the drive of the stage drive mechanism 202.

[0039] In this embodiment, the stage driving mechanism 202 includes a drive motor and a drive belt. The drive belt is connected to the power output end of the drive motor, and the stage 201 is fixedly connected to the belt, so that the stage 201 can move under the drive of the drive motor.

[0040] In addition, to prevent the stage 201 from deviating during movement, in this embodiment, the drive mechanism 20 also includes a guide rail 203. The lower end of the stage 201 is provided with a slider that slides with the guide rail 203. The slider can slide along the guide rail 203 to guide the stage 201 and prevent the stage 201 from deviating.

[0041] Furthermore, to prevent the cryopreservation tube held by the clamp 10 from penetrating too deeply into the ultrasonic welding head 30, this embodiment also includes a limiting damping member 60. The limiting damping member 60 is adapted to abut against the slider when the cryopreservation tube held by the clamp 10 reaches the preset processing position, so as to prevent the stage drive mechanism 202 from being blocked. This effectively prevents the assembly from being inserted too deeply into the ultrasonic welding head 30 and failing to weld properly, or from colliding with and deforming the assembly and the ultrasonic welding head 30.

[0042] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
