The interior of the paint spray box 24 is symmetrically provided with two upper liquid storage tanks 47, and a lower liquid storage tank 47 is provided below each upper liquid storage tank 47. Liquid storage tank 412, each upper liquid storage tank 47 is fixedly connected to the first auxiliary sliding rod 46 on both sides, each lower liquid storage tank 412 is fixedly connected to the second auxiliary sliding rod 413 on both sides, the first auxiliary sliding rod 46 and the second auxiliary sliding rod 413 are respectively inserted into the guide groove 415 opened inside the paint spray box 24, and the first auxiliary sliding rod 46 and the second auxiliary sliding rod 413 are both slidably connected to the paint spray box 24, and the surfaces of the upper liquid storage tank 47 and the lower liquid storage tank 412 are installed with paint heads 414.

[0027] The two upper liquid storage tanks 47 have their sides away from each other fixedly connected with a first tooth plate 48, and the two lower liquid storage tanks 412 have their sides away from each other fixedly connected with a second tooth plate 49, two gears 410 are symmetrically arranged inside the paint spray box 24, and a rotating shaft 411 is inserted inside each gear 410, and the ends of the two rotating shafts 411 away from each other are fixedly connected to the paint spray box 24, respectively, and the gears 410 and the rotating shafts 411 are rotatably connected, and the gear 410 is located between the first tooth plate 48 and the second tooth plate 49, and the first tooth plate 48 and the second tooth plate 49 are both meshed and connected with the gear 410.

[0029] It should be noted that: when the slide plate 32 moves in a direction away from the mounting plate 310, the paint is delivered to the radiator, and at this time the external paint delivery pump can be controlled to stop running by the sensor. When the slide plate 32 moves toward the mounting plate 310, the external paint delivery pump can be started again to achieve intermittent spraying of paint from the inside of the paint spray head 414. When the moving direction of the slide plate 32 changes, it is sensed by the sensor to control the start and stop of the external paint delivery pump. When it is away from the mounting plate 310, the radiator is delivered and the pump is stopped. When it is close to the mounting plate 310, the pump is started to spray paint.

[0030] The present invention provides a method through improvement, and its working principle is as follows: First, when using the production line, the production line is connected to an external power source to power the production line, and the radiator to be painted is clamped inside the clamping member 211. The clamping member 211 is relatively common to those skilled in the art, such as a pneumatic clamping member 211: composed of a cylinder, a piston, a piston rod and a clamping claw, etc. The piston drives the piston rod to move through the action of the cylinder, thereby clamping and releasing the workpiece. Here, the radiator is clamped by the clamping member 211, and the second heating plate 27 and the first heating plate 26 are started by the controller to operate the second heating plate 27 and the first heating plate 26, and temperature control switches are installed inside the heating and curing box 23 and the preheating box 25. The temperature inside the heating and curing box 23 and the preheating box 25 is controlled according to the temperature control switch, and the temperature control switch used in the production line is a liquid expansion type temperature control switch. When the temperature rises, the liquid in the temperature bag expands, the pressure increases, and the micro switch is pushed to operate, effectively cutting off or connecting the circuit. When the temperature drops, the liquid contracts, the pressure decreases, and the micro switch will be reset accordingly. The liquid expansion temperature control switch can achieve relatively accurate temperature control according to the characteristics of the liquid and the design of the device. Whether the temperature rises or falls, as long as it is within the designed temperature range, it can work effectively. The temperature of the temperature control switch inside the preheating box 25 is set to 50 degrees, so that the temperature inside the preheating box 25 fluctuates around 50 degrees. The temperature of the temperature control switch inside the heating and curing box 23 is set to 180 degrees, so that the temperature inside the heating and curing box 23 fluctuates around 180 degrees. When the temperature floating range is large, the first heating plate 26 and the second heating plate 27 are automatically started, so that the temperature inside the preheating box 25 and the heating and curing box 23 reaches the required range; Second, the electric push rod 39 is started by an external controller. When the telescopic rod of the electric push rod 39 begins to retract, the slide plate 32 is driven to move toward the direction close to the mounting plate 310. The movement of the slide plate 32 drives the auxiliary shaft 38 to move synchronously, and then drives the stepping push plate 36 to move synchronously. During the movement, the stepping push plate 36 applies a force to the L-shaped top plate 35, so that the L-shaped top plate 35 slides inside the U-shaped card plate 33. During the sliding process of the L-shaped top plate 35, the spring 34 continues to stretch. The chain 210 has a suitable friction force inside the circular track 28. When the auxiliary shaft 38 pulls the stepping push plate 36 to move toward the mounting plate 310, the stepping push plate 36 slides on the surface of the circular chain 210. At this time, the friction force between the stepping push plate 36 and the circular chain 210 cannot drive the circular chain 210 to move, that is, when the telescopic rod of the electric push rod 39 begins to retract, the circular chain 210 does not move, and the radiator below the circular chain 210 does not move. Third, when the telescopic rod of the electric push rod 39 begins to extend, the stepping push plate 36 is pushed to rotate on the surface of the auxiliary rotating shaft 38 through the L-shaped top plate 35 under the action of the elastic potential energy of the spring 34. As the stepping push plate 36 rotates, the stepping push plate 36 is inserted between the two adjacent sleeves at the corresponding position inside the ring chain 210. The ring chain 210 is composed of an inner chain plate, a sleeve, an outer chain plate and a pin shaft. When the stepping push plate 36 is inserted between the two adjacent sleeves inside the ring chain 210, as the telescopic rod of the electric push rod 39 extends, the slide plate 32 is driven to move in the direction away from the mounting plate 310, and the movement of the slide plate 32 drives the auxiliary rotating shaft 38 to rotate. The shaft 38 moves synchronously, thereby driving the stepping push plate 36 to move synchronously. When the slide plate 32 drives the stepping push plate 36 to move in a direction away from the mounting plate 310, the movement of the stepping push plate 36 can drive the ring chain 210 to slide inside the ring track 28 under the support of the limit shaft 37. The movement of the ring chain 210 drives the radiator installed below it to move synchronously. Since the telescopic end of the electric push rod 39 moves back and forth, the radiator below the ring chain 210 is intermittently transported, and the radiator that has been painted is disassembled while the radiator to be painted is installed during the period when the ring chain 210 stops moving. Fourth, since the endless chain 210 drives the radiator below it to be transported intermittently, the radiator below it can stay in the preheating box 25, the paint spraying box 24 and the heating curing box 23 for a suitable time. When the radiator is transported to the preheating box 25 and stays for a suitable time, since the temperature inside the preheating box 25 can fluctuate around 50 degrees, its main purpose is to perform a preliminary preheating treatment on the radiator so that the surface of the radiator reaches a state suitable for subsequent painting operations. For example, at this temperature, the surface of the radiator may undergo slight physical changes, removing some surface The moisture in the paint or slightly activates the surface material, thereby enhancing the adhesion between the paint and the radiator surface. After the paint is sprayed, the radiator is immediately sent to the heating and curing box 23 for heating and curing. When the radiator enters the heating and curing box 23, the temperature control switch inside the heating and curing box 23 is set to 180 degrees, so that the radiator stays in a high temperature environment of 180 degrees for a certain period of time. This period of time is enough for the paint to be fully cured on the radiator surface. During the heating and curing process, the solvent in the paint gradually evaporates, and the resin and other components undergo a cross-linking reaction to form a hard, wear-resistant coating with good adhesion; Fifth, the upper liquid storage tank 47 and the lower liquid storage tank 412 are connected to the external paint liquid delivery pump through pipelines. Under the action of the external paint liquid delivery pump, the paint liquid can be sprayed out along the inside of the paint spray head 414. When the slide plate 32 moves in the direction of the mounting plate 310, the ring chain 210 does not deliver the paint at this time, so that the radiator inside the paint spray box 24 does not move, and when the slide plate 32 moves toward the mounting plate 310, it drives the U-shaped block 45 to move synchronously. The movement of the U-shaped block 45 drives the inclined rod 43 connected thereto to move, and then drives the upper cross bar 41 to move. Under the restriction of the vertical movement of the longitudinal insertion rod 42, the upper cross bar 41 moves vertically, that is, when the U-shaped block 45 moves to the lower part of the upper cross bar 41, the upper cross bar 41 is in a state of vertical upward movement, and when the U-shaped block 45 moves from the lower part of the upper cross bar 41 to the mounting plate 310, the upper cross bar The upper and lower liquid storage tanks 47 and 412 are moved back and forth during the vertical reciprocating movement of the upper cross bar 41, and the movement of the upper liquid storage tank 47 drives the first tooth plate 48 to move synchronously. The first tooth plate 48 drives the gear 410 meshing with it to rotate during the movement, thereby driving the second tooth plate 49 to move, thereby realizing that the paint spraying head 414 moves upward when the upper liquid storage tank 47 moves downward, and the lower liquid storage tank 412 moves downward when the upper liquid storage tank 47 moves upward, and the reciprocating movement of the upper cross bar 41 causes the upper liquid storage tank 47 and the lower liquid storage tank 412 to move back and forth, thereby realizing uniform painting of the radiator. When the radiator is transported to the interior of the paint spraying box 24, the upper liquid storage tank 47 and the lower liquid storage tank 412 respectively drive multiple paint spraying heads 414 to move back and forth, and the paint liquid is sprayed from the interior of the paint spraying heads 414, which is conducive to uniform painting of the radiator.
