The consumables are equipped with a chip that is used to store relevant information about the consumables, such as the consumable model, production date, manufacturer, serial number, chip program version, and other attribute information. As the consumable model is updated, the current program content in the chip needs to be overwritten and updated. This requires the use of a chip reader / writer to burn the chip program (i.e., write data), which is to "rework" the chip that needs to be upgraded. The "rework" process may include modifying, adding, or deleting the data or program stored in the chip, as well as testing and confirmation after performing the above operations.

[0053] Chip reading and writing include two operations: reading chip programs and burning chip programs. Burning the chip program can overwrite the current program content in the chip.

[0054] Current chip reading and writing devices usually include a device body and a test head. The device body and the test head are separately set and connected via a data cable or wireless means such as Bluetooth. A start button or display screen is provided on the device body. When the user reworks the chip, he needs to hold the test head with one hand to align and press the chip, and press the start button of the device body with the other hand. He needs to take into account both keeping the test head in contact with the chip and observing the operation progress of the host interface of the device body. It is not very convenient to use and the experience is not good. In addition, the device body and the test head are connected with a data cable for communication. There is interference with the signal due to the length of the cable. The communication speed is also greatly affected by the length of the cable, and it is impossible to achieve the optimal speed.

[0055] In view of this, the present application discloses a chip reading and writing device, which is small in size, easy to carry, and convenient for users to operate. During operation, the user can hold the handheld part with one hand and control the use posture of the test needle through the handheld part so that the test needle is aligned with the chip. At the same time, the hand holding the handheld part can also operate the start button on the handheld part at the same time, and then display the relevant information through the display panel. The user can observe the contact status of the test needle and the chip and the relevant information displayed on the display panel at the same time, which is more convenient to use and easy to operate.

[0056] The chip reading and writing device provided in the embodiments of the present application is described below with reference to the accompanying drawings.

[0057] As shown in FIG1 , an embodiment of the present application discloses a chip reading and writing device, which includes a handheld portion 1 and a test portion 2. The handheld portion 1 includes a first connection end, and the test portion 2 includes a second connection end. The second connection end can be detachably plugged into the first connection end to achieve detachable plugging of the handheld portion 1 and the test portion 2. The handheld portion 1 is used for holding by the user's hand, and the test portion 2 is used to perform read and write operations on the chip. When in use, the first connection end of the handheld portion 1 can be plugged into the second connection end of the test portion 2 so that the test portion 2 is located at one end of the length direction of the handheld portion 1. At this time, the test portion 2 is electrically connected to the handheld portion 1. The user can hold the handheld portion 1 and control the test needle 22 of the test portion 2 to align with and contact the chip contacts, and then perform related operations to achieve read and write operations on the chip. When not in use, the handheld portion 1 and the test portion 2 can be separated for easy storage or maintenance.

[0058] 1 and 2 , the handheld device 1 includes a handheld body 11, a display panel 12, a first conductive portion 13, a test button 16, and an operating button 15. The handheld body 11 is disposed along the length of the chip reader / writer (direction X in FIG3 ), and has a first connection end, a front surface 11a, a side surface 11c, and a top surface 11b. The front surface 11a, the side surface 11c, and the top surface 11b intersect with each other. The test button 16 includes a start button 14. The display panel 12, the start button 14, and the operating button 15 are respectively disposed on the front surface 11a. The display panel 12 is used to display relevant information about the burning process. The start button 14 is used to start or stop the burning process. The operating button 15 can be located above, below, on the left, or on the right side of the display panel 12. The operating button 15 is used for interactive input of the display panel 12. The first conductive portion 13 is disposed at the first connection end. The test unit 2 includes a test unit body 21, a test pin 22, and a second conductive portion 23. The test unit body 21 can be located at one end of the chip reader / writer device in the longitudinal direction. The test unit body 21 has a test end and a second connection end that are interconnected. The second conductive portion 23 is located at the second connection end, and the test pin 22 is located at the test end. The test pin 22 includes a data interface for communicating with the chip. Furthermore, the test pin 22 can be located at the end of the test unit 2 so that the test pin 22 can contact the contacts of the chip to be burned, and the test pin 22 is electrically connected to the second conductive portion 23.

[0059] When the first connection end of the handheld portion 1 and the second connection end of the test portion 2 are in a plugged-in state (i.e., the handheld portion 1 and the test portion 2 are in a plugged-in state), the first conductive portion 13 and the second conductive portion 23 abut against each other, achieving electrical connection, thereby achieving communication connection between the test needle 22 and the first conductive portion 13. At this time, the display panel 12 is located at the end of the handheld portion body 11 away from the test portion 2, and the start button 14 is located between the display panel 12 and the test portion 2. That is, the display panel 12, the start button 14, and the test portion 2 are spaced apart along the length direction of the chip reading and writing device, and the use posture of the test needle 22 can be controlled by the handheld portion 1. For example, by holding the handheld portion 1, it is convenient to control the position of the test needle 22, the conduction and read / write status of the test needle 22, etc.

[0060] In this embodiment, the test unit 2 is connected to the handheld unit 1 by plugging and unplugging, omitting the connecting wires, and a display panel 12 is provided on the handheld unit 1, so that the whole chip reading and writing device is set as an integrated portable structure, which is convenient for user management and use.

[0061] In some embodiments, the first conductive part 13 can be a communication contact, and the first conductive part 13 can also be a contact pin, such as a spring pin (POGO pin), so that the first conductive part 13 is connected to the second conductive part 23 of the test part 2 to play a signal transmission role, or the second conductive part 23 and the first conductive part 13 can also be connected through an adapter.

[0062] In this embodiment, the start button 14 and the display panel 12 are both arranged on the front surface 11a, and the display panel 12, the start button 14 and the test part 2 are arranged in sequence from top to bottom along the length direction of the handheld part 1, so as to facilitate handheld operation and observation of the burning process. The handheld position will not block the screen and is close to the test part 2, so that the center of gravity of the test is moved downward, the contact is more stable, and the jitter during the test process is reduced. At the same time, the display panel 12 and the start button 14 are arranged on the same surface and in an upper position, so that the burning process displayed on the display panel 12 is facing the operator and closer to the operator's eyes, which is convenient for observation.

[0063] In some embodiments, the start button 14 can be a mechanical button or a touch button. The display panel 12 can be a touch screen, and interactive operations with the chip reader / writer device can be performed by touching the touch screen. The operating button 15 includes, but is not limited to, at least one of a key and a knob. The operating button 15 can also include a power button for starting and shutting down the chip reader / writer device. Of course, the operating button can also be omitted, and interactive operations can be performed through the touch screen.

[0064] In some embodiments, there are multiple test pins 22, each of which includes a power output interface and a data interface. The power output interface is used to provide power to the chip, and the data interface is used to perform subsequent reading and writing on the chip. In other embodiments, the power output interface and the data interface can also be integrated together to accommodate different chips.

[0065] Furthermore, the shape of the test needle 22 includes but is not limited to a cylindrical shape, a polygonal column shape, etc., and can be selected according to the contacts of the chip to be burned, so as to be suitable for different chips to be burned, thereby improving the versatility of the chip reading and writing device. The arrangement shape of multiple test needles 22 is not specifically limited in this application.

[0066] In some embodiments, the handheld body 11 has multiple finger contact positions. When the display panel 12 faces the user, one of the multiple finger contact positions faces the user, and the remaining finger contact positions are located on the side of the handheld 1. The test button 16 can be located at one of the finger contact positions.

[0067] To facilitate gripping by the user, the handle 1 is configured as a rectangular parallelepiped. Specifically, the handle 1 is longer in the longitudinal direction (e.g., the X-axis direction in FIG1 ) than in other perpendicular directions. For example, the handle 1 can be considered as a rectangular parallelepiped, where the length of the handle 1 is greater than its width or thickness.

[0068] In an embodiment of the present application, the display panel 12, the start button 14 and the test part 2 are spaced apart along the length direction of the chip reading and writing device, that is, they are staggered with each other in the length direction of the handheld part 1 to avoid blocking the display panel 12 and the test part 2 when the human hand holds the handheld part 1 in the length direction.

[0069] In this embodiment, the length of the hand-held portion 1 in any direction perpendicular to the length direction of the hand-held portion 1 is less than or equal to 10 cm, that is, the length of the hand-held portion 1 in both the width direction and the thickness direction is less than or equal to 10 cm. The distance between the start button 14 and the test pin 22 is greater than or equal to 3 cm. The distance from the base of the thumb to the farthest joint of the finger of an average person does not exceed 10 cm. Therefore, the length and width of the hand-held portion 1 should not be too large. It should be ensured that it is within this range to facilitate the human hand to hold and press the start button 14. In addition, the distance between the start button 14 and the test pin 22 should not be too small. When the human hand grasps, the thumb can contact the start button 14 located on the front surface 11a. It should not deviate too much. It is best for the thumb to contact in parallel. At this time, the distance between the thumb and the lowermost little finger is about 3 cm. Therefore, the distance between the start button 14 and the test pin 22 is greater than or equal to 3 cm to prevent the little finger from interfering with the burning operation.

[0070] Furthermore, the length of the handheld portion 1 in the longitudinal direction is greater than or equal to twice the length in other perpendicular directions; the handheld portion 1 forms a long strip structure, which is easy for the human body to grasp, and leaves enough space to set the display panel 12 and the start button 14.

[0071] In this embodiment, the test direction of the chip reader / writer during the programming test is located along the length of the handheld portion 1. In other embodiments, the test direction of the chip reader / writer during the programming test may also be set at an angle to the length of the handheld portion 1. For example, the test needle 22 may be set at an angle at the bottom of the handheld portion 1 to facilitate observation when the test needle 22 is aligned with the chip contacts.

[0072] In actual application scenarios, the user can hold the handheld part 1 with one hand and align the test needle 22 with the chip. At the same time, the hand holding the handheld part 1 can also operate the handheld part 1 and display relevant information on the display panel 12. At this time, the user can observe the contact between the test needle 22 and the chip while also observing the relevant information displayed on the display panel 12. In addition, the user can start burning with one click, which is more convenient to use and easy to operate.

[0073] In this embodiment, the display panel 12 is positioned at the end of the handheld body 11 away from the test unit 2 (i.e., the test unit 2 is at the bottom and the display panel 12 is at the top), thereby placing the programming process closer to the user's eyes and making it easier to observe. Furthermore, the start button 14 is located below the display panel 12, that is, between the display panel 12 and the test unit 2. During programming, the user holds the handheld body 1 in the middle, making it easier for the finger to contact and press the start button 14. Furthermore, placing the start button 14 close to the test unit 2 can reduce the deviation of the test probe 22 caused by the force applied to one side of the handheld body 1 when pressed, thereby avoiding programming failures.

[0074] When in use, the user usually holds the device with the thumb on the human-computer interface facing the user, and four fingers on the back to form a grip, which makes it easy to hold the chip reading and writing device, and also easy to operate and view the display panel 12. At this time, the thumb is used to operate and select the operation button 15, and the start button 14 is used to confirm the burning.

[0075] 2 , to facilitate the connection between the handheld unit 1 and the test unit 2, one of the handheld unit body 11 and the test unit body 21 is provided with a mounting cavity 110, and the other is provided with a connecting portion 210. The connecting portion 210 can be plugged into the mounting cavity 110 to facilitate the connection between the handheld unit 1 and the test unit 2. By plugging and unplugging the connecting portion 210 into the mounting cavity 110, this embodiment improves the stability of the connection between the handheld unit 1 and the test unit 2.

[0076] In some embodiments, the handheld part 1 may be a female plug and the test part 2 may be a male plug. Of course, the handheld part 1 may also be a male plug and the test part 2 may be a female plug. For example, in this embodiment, the first connection end of the handheld part body 11 is provided with a mounting cavity 110, and the second connection end of the test part body 21 is provided with a connection part 210. The connection part 210 can be directly plugged in and connected to the mounting cavity 110, so that the handheld part 1 and the test part 2 are connected as a whole, achieving a stable connection effect between the handheld part 1 and the test part 2, and eliminating the need for wires for signal transmission between the device host in the handheld part 1 and the test part 2, which can effectively solve the signal interference problem caused by the line length. Among them, the plug-in and unplugging direction of the test part 2 is the direction indicated by the arrow X in Figure 1.

[0077] Of course, in other embodiments, the second connection end of the test part body 21 may be provided with a mounting cavity 110, the first connection end of the handheld part body 11 may be set as a connection part 210, and the connection part 210 of the handheld part 1 can be plugged into and unplugged from the mounting cavity 110 of the test part 2, so that the handheld part 1 and the test part 2 are connected as a whole by directly plugging and unplugging the connection part 210 into the mounting cavity 110, thereby achieving a stable connection effect between the handheld part 1 and the test part 2, and eliminating the need to use wires for signal transmission between the handheld part 1 and the test part 2, which can effectively solve the signal interference problem caused by line length.

[0078] In order to make the insertion and removal between the handheld body 11 and the test part body 21 more stable, the chip reading and writing device also includes a separation part, which is provided on one of the handheld body 11 and the test part body 21, and is used to lock or separate the handheld part 1 and the test part 2. The separation part can be electromagnetic or mechanical, as long as it can achieve rapid locking or separation of the handheld part 1 and the test part 2. Exemplarily, the chip reading and writing device also includes a first clamping part 111 and a second clamping part 24, the first clamping part 111 is provided on the handheld body 11, and the second clamping part 24 is provided on the test part body 21, and the second clamping part 24 and the first clamping part 111 can be mutually engaged and connected to lock the handheld part 1 and the test part 2. One of the first clamping part 111 and the second clamping part 24 is an elastic snap (the elastic snap can be regarded as a separation part), and the other is a card slot.

[0079] In this embodiment, two first engaging portions 111 and two second engaging portions 24 are provided, respectively. A first engaging portion 111 is provided on each side wall of the mounting cavity 110, and the first engaging portion 111 is configured as a slot. A second engaging portion 24 is provided on each side wall of the test portion body 21, and the second engaging portion 24 is configured as an elastic snap. The positions of the two elastic snaps correspond to the positions of the two slots, and the two elastic snaps can respectively cooperate with the two slots to engage with each other to lock or separate the handheld portion 1 and the test portion 2. For example, when the elastic snap is engaged with the slot, the elastic snap itself undergoes elastic deformation to fit into the slot, and after fitting into the slot, the deformation is restored, thereby allowing the connecting portion 210 to be stably clamped in the mounting cavity 110, ensuring a stable connection between the handheld portion 1 and the test portion 2.

[0080] In some embodiments, the first engaging portion 111 may be an elastic buckle, and the second engaging portion 24 may be a slot, and the elastic buckle and the slot are engaged with each other to improve the stability of the connection between the handheld portion 1 and the testing portion 2.

[0081] To further improve the stability of the connection between the handheld unit 1 and the test unit 2, the chip reader / writer device also includes a first magnetic member and a second magnetic member. The first magnetic member is disposed in the mounting cavity 110, and the second magnetic member is disposed in the connecting portion 210. The second magnetic member and the first magnetic member are disposed in a position corresponding to each other, and the second magnetic member and the first magnetic member can be mutually attracted and fixed. When the test unit 2 is inserted into the mounting cavity 110, the second magnetic member and the first magnetic member are attracted to each other, thereby hindering the separation of the test unit 2 and the handheld unit 1 under the action of magnetic attraction, thereby improving the stability of the connection between the test unit 2 and the handheld unit 1.

[0082] In this embodiment, the first magnetic member and the second magnetic member are both magnets. In some embodiments, the first magnetic member may be a magnet and the second magnetic member may be an iron sheet or an alloy sheet containing metallic iron, or the second magnetic member may be a magnet and the first magnetic member may be an iron sheet or an alloy sheet containing metallic iron.

[0083] To facilitate the disassembly of the test unit 2 and the handheld unit 1, the chip reading and writing device further includes an elastic member 3. The elastic member 3 is disposed within the mounting cavity 110, and one end of the elastic member 3 is fixed to the inner wall of the mounting cavity 110, thereby preventing the elastic member 3 from detaching from the mounting cavity 110. The elastic member 3 is used to facilitate the detachment of the connecting portion 210 from the mounting cavity 110. When the test unit 2 and the handheld unit 1 are in a plugged-in state, the two ends of the elastic member 3 abut against the connecting portion 210 and the inner wall of the mounting cavity 110, respectively, and the force applied by the elastic member 3 is in the direction of removal of the test unit 2. In this embodiment, the elastic member 3 may be a compression spring.

[0084] When the test part 2 and the handheld part 1 are in the plugged-in state, the first engaging portion 111 and the second engaging portion 24 engage with each other, clamping the test part 2 and the handheld part 1 tightly and preventing the test part 2 and the handheld part 1 from separating. At this time, the connecting portion 210 squeezes the elastic member 3, causing the elastic member 3 to compress and accumulate force and maintain the compressed state. At the same time, when the first conductive portion 13 is a spring needle, since both the first conductive portion 13 and the elastic member 3 are squeezed, a double thrust is generated. When it is necessary to remove the test part 2 from the handheld part 1, the elastic buckle can be manually pressed to separate the first engaging portion 111 and the second engaging portion 24. At this time, under the elastic force of the elastic member 3, the connecting portion 210 can be easily removed from the mounting cavity 110 without any effort, so that the test part 2 and the handheld part 1 are separated.

[0085] In order to improve the plugging accuracy between the test part 2 and the handheld part 1, the chip reading and writing device further includes a first positioning part (not shown in the figure) and a second positioning part (not shown in the figure). The first positioning part is provided in one of the mounting cavity 110 and the connecting part 210, and the second positioning part is provided in the other of the mounting cavity 110 and the connecting part 210. The second positioning part and the first positioning part can cooperate with each other to position the connecting part 210 in the mounting cavity 110. One of the first positioning part and the second positioning part can be a protrusion, and the other of the first positioning part and the second positioning part can be a groove. By correspondingly extending the protrusion into the groove, the accuracy of the corresponding contact between the second conductive part 23 and the first conductive part 13 can be improved, thereby preventing the occurrence of misalignment and affecting the communication stability.

[0086] In this embodiment, the first positioning portion is provided on the inner wall of the installation cavity 110 and is configured as a groove, and the second positioning portion is provided on the outer wall of the connecting portion 210 and is configured as a protrusion.

[0087] In order to facilitate the disassembly and installation of the test part 2, an assembly groove 112 is opened on the inner wall of the installation cavity 110. When the connecting part 210 is located in the installation cavity 110, there is a gap between the inner surface of the assembly groove 112 and the outer surface of the connecting part 210. The gap can reduce the contact area between the connecting part 210 and the inner wall of the installation cavity 110, thereby reducing the friction and making the installation or removal of the test part 2 smoother.

[0088] Because the first conductive portion 13 and the second conductive portion 23 must be aligned and connected to ensure effective contact, when the test unit 2 and the handheld unit 1 are plugged in, the gap between the connecting portion 210 and the inner wall of the mounting cavity 110 needs to be small. This may cause high friction when inserting and removing the test unit 2, making it difficult to remove the test unit 2. Therefore, by providing the assembly groove 112 in this embodiment, the contact area between the connecting portion 210 and the inner wall of the mounting cavity 110 can be reduced, making the insertion and removal of the test unit 2 more labor-saving.

[0089] In order to facilitate the guidance of the insertion direction of the test part 2, the chip reading and writing device further includes a first guide portion 17 and a second guide portion 211. The first guide portion 17 is provided on one of the inner wall of the installation cavity 110 and the outer wall of the connecting portion 210, and the second guide portion 211 is provided on the other of the inner wall of the installation cavity 110 and the outer wall of the connecting portion 210. The positions of the first guide portion 17 and the second guide portion 211 are correspondingly provided, and are used to guide the connecting portion 210 when the connecting portion 210 is inserted into the installation cavity 110. Among them, one of the first guide portion 17 and the second guide portion 211 is provided as a guide groove, and the other of the first guide portion 17 and the second guide portion 211 is provided as a guide protrusion, and the guide protrusion can slide in cooperation with the guide groove.

[0090] In some embodiments, the guide groove extends along the insertion and removal direction of the test part 2, and the cross section of the guide groove can be rectangular, semicircular, etc. The cross section of the guide protrusion is consistent with that of the guide groove, which is conducive to improving the guiding effect.

[0091] In this embodiment, the first guide portion 17 is provided on the inner wall of the mounting cavity 110 and is configured as a guide protrusion, and the second guide portion 211 is provided on the outer wall of the connecting portion 210 and is configured as a guide groove. Of course, in other embodiments, the first guide portion 17 may be a guide groove and the second guide portion 211 may be a guide protrusion.

[0092] This embodiment, through the sliding fit of the guide protrusion and the guide groove, guides the test unit 2 as it is installed within the handheld unit 1, helping to prevent the test unit 2 from becoming skewed or stuck during installation. Furthermore, during installation, if the second guide portion 211 is misaligned with the first guide portion 17, the connecting portion 210 will not fit within the installation cavity 110. This also prevents the test unit 2 from being installed upside down, thus providing a foolproofing feature.

[0093] Based on the above embodiment, the present application also discloses another specific implementation method. The difference between this embodiment and the above embodiment is that, in this embodiment, as shown in Figure 3, the plane where the start button 14 is located is set at an angle to the plane where the display panel 12 is located. For example, the display panel 12 can be set on the front surface 11a of the hand-held part 1, and the start button 14 can be set on the side surface 11c of the hand-held part 1.

[0094] After testing, it was found that when the start button 14 and the display panel 12 are both set on the front surface 11a of the handheld part 1, after the test needle 22 fixed on the test part 2 is aligned with the contact of the chip to be burned, because the thumb does not press the start button 14 tightly at the beginning, the palm of the hand is not under force, and the grip force on it is suspended. Then, in the process of pressing the start button 14 with the thumb, the grip force gradually increases, and there will be uncontrollable jitter, which may cause the test needle 22 to deviate from the chip contact, resulting in burning failure.

[0095] In this embodiment, the handle body 11 is provided with a plurality of finger contact positions, including a thumb contact position, an index finger contact position, a middle finger contact position, a ring finger contact position, and a pinky finger contact position. The thumb contact position may also be located on the top surface 11b of the handle 1, and the remaining four finger contact positions are located on the side surface 11c of the handle 1.

[0096] The start button 14 can be located on the side surface 11c of the handheld portion 1. Specifically, the start button 14 can be located at the four finger contact positions other than the thumb contact position. For example, the start button 14 can be located at the position where the side surface 11c of the handheld portion 1 contacts the index finger, i.e., the index finger contact position, or at the other three finger contact positions other than the user's palm, thumb, and index finger contact positions. Before and after pressing the start button 14, the handheld portion 1 can always be gripped tightly, and there is an enveloping grip. After the index finger presses the start button 14, the gripping force significantly reduces the shaking force, thereby allowing stable burning.

[0097] In this embodiment, the start button 14 is set on the side surface 11c of the hand-held part 1. It does not have to be a straight side surface perpendicular to the front surface 11a where the display panel 12 is located. It can also be set at a certain angle so that it is easier to access when the finger is bent around the hand-held part 1, as shown in Figure 3.

[0098] In some embodiments, the start button 14 can also be positioned at the position where the top surface 11b of the handheld portion 1 contacts the thumb, that is, at the thumb contact position on the top surface 11b of the handheld portion 1. Before and after pressing the start button 14, the palm and the other four fingers form a gripping force, which can also reduce jitter and ensure stable burning. Furthermore, the projections of the start button 14 and the midpoint of the test portion 2 in the length direction of the handheld portion 1 overlap. In this embodiment, by overlapping the projections of the start button 14 and the midpoint of the test portion 2 in the length direction of the handheld portion 1, the force applied when pressing the start button 14 can be as close to the center of the test portion 2 as possible, further reducing jitter.

[0099] Based on the above embodiment, the present application also discloses another specific embodiment. The difference between this embodiment and the above embodiment is that, in this embodiment, as shown in Figures 4 and 5, the chip reading and writing device also includes a first protective sleeve 4. The first protective sleeve 4 is provided with a first protective cavity 40. The first protective cavity 40 is used to accommodate the test part 2 in the plugged state, so as to protect the test needle 22 during the temporary movement process when the burning device stops burning. Specifically, when the test part 2 and the handheld part 1 are in the plugged state, the test part 2 can be at least partially inserted into the first protective cavity 40, so that the opening of the first protective sleeve 4 is connected to the handheld part 1 or the test part 2, thereby protecting the test part 2 through the first protective sleeve 4.

[0100] Because the test needle 22 is relatively easy to damage, the first protective cover 4 is mainly used to protect the test needle 22 of the test unit 2. When the test unit 2 and the handle 1 are connected to each other, the open end of the first protective cavity 40 can be connected to the handle 1 to cover the test unit 2 within the first protective cavity 40, thereby effectively protecting the test unit 2.

[0101] In some embodiments, the first protective cover 4 can be connected to the handheld portion 1 or the testing portion 2 by snapping. For example, a mounting buckle 18 can be provided on the outer surface of the handheld portion 1, and a recess can be provided on the inner wall of the first protective cavity 40. When the chip reader / writer device is inserted into the first protective cavity 40, the mounting buckle 18 can snap into the recess, thereby enhancing the securing effect of the first protective cover 4 after being fixed and preventing the first protective cover 4 from loosening.

[0102] In order to match the structures of the testing part 2 and the handheld part 1 , an outer convex groove 41 is provided at the open end of the first protective cover 4 , and the outer convex groove 41 is used to accommodate the elastic buckle.

[0103] In this embodiment, the first protective cover 4 is provided to protect the test needle 22 when the chip reading and writing device stops burning or is temporarily moved, thereby reducing the probability of the test needle 22 being damaged by collision.

[0104] Based on the above embodiment, the present application also discloses another specific implementation method. The difference between this embodiment and the above embodiment is that, in this embodiment, as shown in FIG6 , the chip reading and writing device further includes a second protective cover 5. The second protective cover 5 and the first protective cover 4 can be connected in cooperation to form a receiving chamber 50. The receiving chamber 50 is used to accommodate the test part 2 in a separated state. Specifically, when the test part 2 and the handheld part 1 are separated from each other, the test part 2 can be accommodated in the receiving chamber 50. Thus, through the cooperation between the first protective cover 4 and the second protective cover 5, the test part 2 is protected, and the first protective cover 4 achieves a dual-purpose effect.

[0105] To guide the insertion of the test unit 2 into the second protective cover 5, a third guide portion 51 is provided on the inner wall of the second protective cover 5. The position of the third guide portion 51 corresponds to the position of the second guide portion 211 provided on the outer wall of the connecting portion 210. The third guide portion 51 and the second guide portion 211 slide together to prevent the second protective cover 5 from being misaligned or installed upside down, thus providing a foolproof effect. One of the third guide portion 51 and the second guide portion 211 is a guide groove, and the other is a guide protrusion.

[0106] In this embodiment, the second guide portion 211 can be configured as a guide groove, and the third guide portion 51 can be configured as a guide protrusion. The extension direction of the guide protrusion is consistent with the installation direction of the second protective cover 5, and the guide protrusion can slide along the guide groove to guide the installation and removal of the second protective cover 5. Of course, in some embodiments, the third guide portion 51 can also be configured as a guide groove, and the second guide portion 211 can be configured as a guide protrusion.

[0107] In some embodiments, the first protective cover 4 can be connected to the second protective cover 5 by snapping together. Exemplarily, the side wall of the second protective cover 5 is provided with a snap-fitting groove 52 and a snap-fitting buckle 53. When the test part 2 is accommodated in the accommodating cavity 50 composed of the first protective cover 4 and the second protective cover 5, the separation portion provided on the outer wall of the test part 2 extends to the outside of the second protective cover 5 through the snap-fitting groove 52, and the separation portion and the snap-fitting groove 52 are snap-fitted together. The snap-fitting buckle 53 is snap-fitted and connected to the inner wall of the first protective cover 4, thereby ensuring a stable snap-fitting connection between the first protective cover 4 and the second protective cover 5, and preventing the first protective cover 4 and the second protective cover 5 from detaching from the test part 2.

[0108] In this embodiment, the separation portion is an elastic buckle, and the engagement groove 52 is a slot extending through the side wall of the second protective sleeve 5. The inner wall of the first protective sleeve 4 is provided with a recessed portion that matches the shape of the engagement buckle 53. By embedding the engagement buckle 53 in the recessed portion, the stability of the connection between the first protective sleeve 4 and the second protective sleeve 5 can be improved.

[0109] When the test section 2 and the handheld section 1 are separated from each other and the test section 2 needs to be stored, the test section 2 can be placed in the second protective cover 5, with the separation portions on both sides of the test section 2 passing through the fitting grooves 52 and engaging with the fitting grooves 52 to fix the second protective cover 5 relative to the test section 2. The second protective cover 5 is then fitted onto the first protective cover 4. With the fitting buckles 53, a stable fitting connection between the first and second protective covers 4 and 5 is achieved, thereby protecting the test section 2. At this point, the separation portions on both sides of the test section 2 are accommodated in the outer convex grooves 41 of the first protective cover 4, providing all-round protection for the test section 2, preventing dust from falling into the test section 2, and facilitating storage of the test section 2.

[0110] In some embodiments, the fitting groove 52 and the first engaging portion 111 have the same structure, and the fitting buckle 53 and the installation buckle 18 have the same structure, so that the handheld body 11 and the second protective cover 5 are both suitable for fitting the first protective cover 4 .

[0111] Based on the above embodiment, the present application also discloses another specific implementation method. The difference between this implementation method and the above embodiment is that, in this embodiment, as shown in Figures 7 and 8, the chip reading and writing device also includes a card clip 6, which is used to facilitate the fixed installation of the plugged handheld part 1 and the test part 2 on the work station.

[0112] The clip 6 includes a back plate 61, a first clamping portion 62, and a second clamping portion 63. The first clamping portion 62 and the second clamping portion 63 are respectively connected to the two sides of the back plate 61, so that a clamping cavity 60 is formed between the first clamping portion 62 and the second clamping portion 63. The clamping cavity 60 is used to clamp the handheld device 1. When the handheld device 1 is located in the clamping cavity 60, the first clamping portion 62 and the second clamping portion 63 are respectively clamped on the two opposite sides of the handheld device 1, which facilitates the quick removal and installation of the handheld device 1 without the need for screws, making it easy to use.

[0113] In some embodiments, the first clamping portion 62, the second clamping portion 63, and the back plate 61 can be an integrally connected structure. For example, the first clamping portion 62 and the second clamping portion 63 can be formed by bending the two sides of the back plate 61 toward the handheld portion 1, which has a simple structure and is easy to use.

[0114] To facilitate positioning of the handheld portion 1 within the clamping cavity 60, the chip reading and writing device further includes a third positioning portion 113 and a fourth positioning portion 64. The third positioning portion 113 is provided on the handheld portion body 11, and the fourth positioning portion 64 is provided on the back plate 61. Through the cooperation between the third positioning portion 113 and the fourth positioning portion 64, the position of the handheld portion 1 within the clamping cavity 60 can be positioned. One of the third positioning portion 113 and the fourth positioning portion 64 is configured as a positioning groove, and the other is a positioning post, which can extend into the positioning groove.

[0115] In this embodiment, the third positioning portion 113 can be configured as a positioning groove, and the fourth positioning portion 64 can be configured as a positioning post. When the handheld portion 1 is assembled on the clip 6, the positioning post can be inserted into the positioning groove to achieve a positioning effect of the handheld portion 1 in the clip 6. Of course, in other embodiments, the third positioning portion 113 can also be configured as a positioning post, and the fourth positioning portion 64 can be configured as a positioning groove.

[0116] In one embodiment, a screw hole 610 is provided on the back panel 61. During installation, a screw can be inserted into the screw hole 610, and then the clip 6 is first fixed to the tooling equipment by the screw, and then the hand-held part 1 is clamped in the clamping cavity 60, and the third positioning part 113 and the fourth positioning part 64 cooperate with each other to achieve the clamping and fixing effect of the hand-held part 1.

[0117] In some embodiments, heat dissipation holes 117 are respectively provided on both sides of the handheld portion 1 , and air convection is achieved through the heat dissipation holes 117 , thereby allowing the handheld portion 1 to dissipate heat faster.

[0118] The chip reading and writing device described in the above embodiment also includes a program burner (not shown in the figure) and a device host (not shown in the figure). The program burner is arranged in the test part body 21, and the test needle 22 and the second conductive part 23 are electrically connected to the program burner respectively. The device host is arranged in the handheld part body 11 and integrated with the handheld part body 11 into an integrated structure. The display panel 12, the first conductive part 13, the start button 14, and the operation button 15 are electrically connected to the device host respectively. When the test part 2 and the handheld part 1 are in the plugged state, the test part 2 is electrically connected to the device host set in the handheld part 1, wherein the display panel 12 is used to display the human-computer interaction content of the device host; the test part 2 is used to send the test program sent by the device host to the chip; the start button 14 is used to control the device host to start or stop sending the test program to the test part 2; and the device host is used to obtain the burning program carried by the program burner.

[0119] It's easy to understand that the device host includes a CPU, memory, a network communication module (wired or wireless), and other components, which implement functions such as human-machine interface display, software function control, test unit control, and network upgrade control. A program burner, also known as a program editor, typically includes a main control board, a storage device for storing the program to be burned, and an interface for writing the program. When the test unit 2 and the handheld unit 1 are connected to each other, the second conductive portion 23 is electrically connected to the first conductive portion 13, establishing electrical continuity between the test unit 2 and the device host in the handheld unit 1, allowing the device host to access the burning program carried by the program burner.

[0120] In this embodiment, the test unit 2 and the device host do not need to be connected by a connecting wire, which reduces the interference of the wire length on the signal. In addition, the test host device host and the handheld unit 1 are integrated together for easy operation and can also make the entire burning device more simplified and compact.

[0121] In some embodiments, the device host can also be provided separately from the handheld unit 1. The handheld unit 1 equipped with the test unit 2 can be connected to the device host via a wired or wireless connection. When performing the programming operation, the user can focus on observing the display panel 12 of the handheld unit 1 and operating the start button 14, without having to devote too much attention to the device host.

[0122] In this embodiment, the program burner is disposed in the test section 2, and the program burner of each test section 2 stores a corresponding different burning program. Therefore, by replacing the test section 2 connected to the handheld section 1, different burning programs can be selected. There is no need to store a large number of burning programs for selection in the device host of the handheld section 1. This makes the entire burning device compact and highly versatile.

[0123] When a new chip or new program needs to be burned, only the test unit 2 storing the updated burning program needs to be replaced. There is no need to upgrade the device host in the handheld unit 1, making it more convenient to use. At the same time, because the handheld unit 1 integrates the device host, the entire burning device is relatively small. The test unit 2 is directly installed inside the handheld unit 1, and the handheld unit 1 has a built-in battery, so no wires are required. The handheld unit 1 can be operated with one hand, such as selecting functions, setting parameters, and writing and testing chips. In addition, the device host in the handheld unit 1 and the test unit 2 do not require wires to connect. Instead, they are connected using a POGO PIN, which helps reduce signal interference.

[0124] In some embodiments, the handheld device 1 further includes a battery and an indicator light 7. The battery is disposed within the handheld device body 11 and is used to provide power to the device host. The indicator light 7 is disposed within the handheld device body 11 and is electrically connected to the device host. The indicator light 7 may be located on the bottom surface of the handheld device 1 and can indicate the power status, programming status, and alignment status of the chip to be programmed, as shown in FIG9 .

[0125] In some embodiments, the handheld device 1 is further provided with a lanyard slot 114, a charging port 115, and a speaker hole 116. The lanyard slot 114, the charging port 115, and the speaker hole 116 may be located on the bottom surface of the handheld device 1. The lanyard slot 114 allows the handheld device 1 to be hung on work equipment. The charging port 115 can be used to charge the battery in the handheld device 1, and the speaker hole 116 can be used for audio prompts during human-computer interaction, as shown in FIG9 .

[0126] In the embodiment of the present application, the device host is the main control device, and a printed circuit board is installed inside the device host, so that the burning process can realize functions such as human-machine interface display, software function control, test unit 2 control, and network upgrade control.

[0127] The chip reading and writing device provided in the present application is convenient for the user to hold the handheld part 1 with one hand so that the test needle 22 is aligned with the chip. At the same time, the hand holding the handheld part 1 can also operate the handheld part 1 at the same time, which is simple and convenient to operate.

[0128] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
